N.B., this was a scheduled post, and I was surprised to see that His Holiness took his reflections this morning from the same gospel passage

In response to Jesus’ question, we hear that great Profession of Faith flow right out of Peter’s mouth.  This great profession of faith that we all need to profess every day.

Tu es Christus Filius Dei vivi. Thou art Christ, the Son of the Living God.

Who is Jesus?  He is the Christ, the Son of the Living God.

respondens autem Iesus dixit ei beatus es Simon Bar Iona quia caro et sanguis non revelavit tibi sed Pater meus qui in caelis est.  And Jesus answering, said to him: Blessed art thou, Simon Bar-Jona, because flesh and blood hath not revealed it to thee, but my Father who is in heaven.

Who revealed this to Simon Peter?  God the Father.  This same Father whose Son will be killed on a CROSS for my sins.  Killed on a CROSS for your sins.  For the sins of the whole world.

et ego dico tibi quia tu es Petrus et super hanc petram aedificabo ecclesiam meam et portae inferi non praevalebunt adversum eam.  And I say to thee: That thou art Peter; and upon this rock I will build my church, and the gates of hell shall not prevail against it.

Tu es Petrus.  You are Peter. Et portae inferi non praevalebunt adversum eam.  The gates of hell will not prevail against Her.  Holy Mother Church will prevail in the end.  She will rein.  We may lose the battle, but will win the war.
