But you say to me: Peter, Mary, and the confession of faith.

**Quote:***”But who do you say that I am?” Responding, Simon Peter said, “You are the Christ, the Son of God.”* (Luke 9:20)**Text:**The Twelfth Sunday of Ordinary Time, Year C, centers on the pivotal scene of Peter’s confession in Caesarea Philippi (Luke 9:18-24), one of the most dense passages from Jesus’ public ministry. Jesus first asks the crowd, *”Who do people say I am?”* (Luke 9:20), and then his disciples, *”But who do you say that I am?”* The answer Peter gives, *”You are the Christ, the Son of God”* is recognized by Jesus as correct, followed by a revelation about impending suffering and the radical call to follow: *”Take up your cross daily and follow me”* (Luke 9:23).The liturgical context is rich: the readings for the Twelfth Sunday C include Zechariah 12:10-11.13:1, a prophecy of Jesus’ passion that tradition has applied to Calvary, and Galatians 3:26-29, *”There is neither Jew nor Greek, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus”* – one of the most explicit statements of eschatological unity in Christ. Peter’s confession is thus framed by a prophecy of the pierced One and a vision of unity in Christ: the *”Christ of God”* that Peter confesses is the one who was pierced and unites all in himself.**I. *”But who do you say that I am?”*: The Question That Defines:**Jesus’ question in Luke 9:20 is the most personal, demanding question from the Gospel: not *”What do others think?”* but *”What do YOU think?”*. The answer cannot be delegated to tradition, authority of teachers, or majority opinion. Discipleship demands a personal response that, once given, defines the disciple’s identity as much as it defines Jesus’. *”You are the Christ of God”* is both an affirmation about Jesus and a declaration about oneself: *”I know who You are, and because I know that, I know who I am – someone who follows You.”*The Church’s Christological tradition has developed this response over centuries of debate. The Councils of Nicaea (325), Ephesus (431), and Chalcedon (451) articulated in philosophical language what Peter expressed in everyday language. *”Christ of God”*, the promised Messiah, the Anointed of the Lord, does not yet fully capture the depth of Jesus’ self-revelation, but it is a good starting point. Dogmatic history is the history of deepening this response: from *”Christ of God”* to *”Son of God consubstantial with the Father”* (Nicene Creed) to *”one Person in two natures”* (Chalcedon). Each deepening of the answer presupposes Peter’s initial response.Mary was the first to respond to the question “who is Jesus?” with her whole existence, before the question was explicitly formulated. The “fiat” of the Annunciation (Dictionary of Mariology: Announcement) is an implicit Christological response: by accepting to be the Mother of the Son of the Most High, Mary affirmed who Jesus is even before Jesus began to reveal Himself publicly. This prioritas of Marian faith, a faith that precedes public revelation and founds the disciples’ following, is what tradition describes when it states that Mary is the “first faithful.” She answered Peter’s question before he had even asked it.The phenomenology of Peter’s confession in Luke 9, in contrast with Matthew’s version, is more sober: there is no declaration about the stone and keys of the kingdom, nor the promise of primacy. Luke presents the confession as a moment of discernment on the path of discipleship, without the ecclesiological implications that Matthew will develop. This difference in emphasis between Luke and Matthew is theologically rich: the confession of faith in Jesus is not only the foundation of church structure (Matthew), but also a moment of personal clarification on the way to discipleship (Luke). Both dimensions are necessary and complementary.## II. Peter’s Confession: Foundation and LimitThe immediate sequence after Peter’s confession in Luke 9,21-22 is disturbing: Jesus “told them not to tell anyone” and announced the suffering that was to come, “the Son of Man must suffer much, be rejected by elders, chief priests, and scribes, be killed, and on the third day rise.” The Peter who correctly confessed Jesus’ identity was about to fail to understand Jesus’ mission: Matthew’s version (Mt 16,22) explicitly states what Luke omits. Peter wanted to reject the announcement of the Passion, and Jesus called him “Satan” (Mt 16:23).This dialectic—correct confession and immediate misunderstanding—is the most honest portrait the Gospels offer of human faith: it can be correct in affirmation and limited in implication. To confess “You are the Christ” is a beginning, not an end. It is the gateway to a process of progressive understanding of Jesus’ identity and mission that the disciples will traverse throughout Jesus’ public life, only completing at Easter. Peter’s limitation does not invalidate his confession but reveals that faith confession is the start of a journey, not the completion of a path.The comparison with Mary is enlightening here: Mary too did not fully comprehend what her “fiat” entailed. The episodes in Luke 2, “did you not know that I had to be in my Father’s house?” (Lc 2,49), and John 2, “my hour has not yet come” (Jo 2,4), show moments when Mary did not fully understand Jesus’ mission. But the difference between Mary and Peter lies in their response to misunderstanding: Peter wanted to reject what he didn’t understand. Mary “kept these things in her heart” (Lc 2,51) and allowed them to mature. This difference in attitude—the open-hearted waiting for understanding versus the ego that rejects what challenges—is the difference between Marian and Petrine discipleship at their moment of greatest fragility.# The Papacy of Pope Francis and the Figure of PeterThe magisterium of Pope Francis emphasizes the figure of Peter as an imperfect disciple model that God uses: not the glorious Peter of confession, but the Peter who denied and was reappointed to his mission by the “but I love you” risen Christ (John 21:15-19). This emphasis has significant implications for understanding the petrine primacy: its authority does not rest on the personal perfection of historical Peter or his successors, but on God’s election of the weak to accomplish His purposes. The same principle applies to all discipleship: authentic faith confession does not require prior perfection, but rather the willingness to learn along the way what confession entails.## III. “Take Up Your Cross”: Followership and KenosisThe immediate instruction following the announcement of Christ’s passion in Luke 9:23 is among the most radical in the Gospel: “If anyone wants to come after me, let him deny himself, take up his cross daily, and follow me.” The Lucan specificity of “daily” is absent in Mark and Matthew; Luke transforms the single act of taking up one’s cross into a daily habit, a disposition that marks each day of following, not just crisis moments. Following Jesus takes the form of daily *kenosis*, an emptying of oneself that is not self-destruction but liberation from ego imprisonment.### The Theology of the Cross as KenosisThe theology of the cross as *kenosis* developed from Philippians 2:6-11 (“he humbled himself, taking the form of a servant”), lies at the heart of Pauline christology and has a fundamental mariological dimension: Mary participated in the *kenosis* of her Son throughout her life, not just on the Cross. The “yes” of the Annunciation was an act of *kenosis*, abandoning autonomy for God’s will. The Visitation was *kenosis*, serving others at the expense of herself. The Cross was the most extreme *kenosis*, renouncing her own son, emptying maternality in service of the redemptive mission.### Practical Application of “Take Up Your Cross Daily”The instruction “take up your cross daily” has tangible concrete applications that spiritual tradition has elaborated into various forms. The daily cross is not necessarily the great martyrdom cross; it is the daily renunciation of egoism, patience with irritations, faithfulness to responsibilities when fatigue invites neglect, forgiveness of a familiar who hurt, and presence to an elderly person when strength falters. This pedagogy of the daily cross, ordinary ascetism in common life, is, according to John Paul II in *Salvifici Doloris* (1984), the most universal form of participation in Christ’s redemptive suffering.### Unity in Christ and KenosisGalatians 3:26-29, the second reading for the Twelfth Sunday C, connects following the cross to eschatological unity in Christ: “There is neither Jew nor Greek, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.” The *kenosis* required by following involves renouncing identities that divide us—Jewishness, freedom, masculinity, womanhood—in favor of the unity Christ makes possible. Mary, who lived *kenosis* exemplarily, is the model of this unity; she is revered in every culture, tradition, and continent precisely because her total availability to God made her available to all humanity.## IV. Mary, First Confessor and Model of DiscipleshipThe confession of Peter, “You are the Christ of God,” is the explicit declaration he makes after two years of following Jesus. Mary’s confession, implicit in the “fiat” and explicitly in the Magnificat, precedes Jesus’ public mission. This prioritas of Marian faith over Petrine faith is not a matter of ecclesiastical rivalry but rather complementarity: the faith that founds discipleship (Mary) and the faith that structures the ecclesial community (Peter) are the two pillars of Christian life.The Magnificat, sung at Vespers every day in the Church, is Mary’s most elaborate confession: a theology of salvation expressed in first-person language of praise and prophecy. “My soul glorifies the Lord and my spirit exults in God my Savior,” is her response to the question, “Who is Jesus?”: He is the Savior, the Mighty One who has fulfilled his promises, the Holy One who has filled the hungry with good things. The Magnificat is the first Christology of the New Testament—not an academic reflection on Jesus’ identity but a song born from the experience of salvation.The prophetic dimension of the Magnificat, “All generations will call me blessed” (Lk 1:48), was fulfilled in a way that exceeded any human expectation at the time Mary sang it. Over two millennia, in every language and culture, generations have called Mary “blessed.” This historical fulfillment of the Magnificat’s prophecy is a verifiable “fruit,” by the criterion of Mt 7:16, of Mary’s mission’s authenticity: the tree that bore this fruit of universal veneration and faith sustained in millions of lives over two millennia is, by its fruits, a good tree.The Twelfth Sunday of Ordinary Time invites each believer to renew their response to Jesus’ question: “Who do you say I am?” The liturgical tradition proposes Mary as a model for this renewal: not the abstract answer of scholastic theology but the existential response of the “fiat”: “You are the Lord of my life, and I am your servant. Let it be done to me according to your word.” This response, which Mary gave at the Annunciation and Peter echoed in Caesarea, and which every Christian is invited to give each Sunday, is the foundation for all authentic Christian life: the rock on which the house is built that the storms cannot destroy.
