This Sunday's
Gospel
continues the dialogue between Jesus and Simon, the Rock on which
Jesus will build his Church. What happens is, quite literally,
scandalous. Jesus follows his granting of primacy to the freshly named
Peter with the first prediction of his passion (and resurrection). In
response Peter rebukes Jesus and says, “God forbid. Lord! No
such thing shall ever happen to you.” Whereupon Jesus turns to
Peter with strong words: “Get behind me, Satan! You are an
obstacle to me. You are thinking not as God does, but as human beings
do.” The word behind “obstacle” is
skandalon, literally “stumbling block.” The
foundation stone has become a stumbling stone. “Satan”
(adversary) is already such a shocking term that we scarcely notice
skandalon.
Matthew (and Mark, though not Luke or John) dares to present Peter
opposing Jesus in this matter of a suffering Messiah, apparently
because he knows that Peter eventually learns and accepts the whole
truth, and even loses his own life (in Rome) witnessing to Jesus as
crucified and risen. This foundation-stone-become-stumbling-stone
stands as a cautionary tale for all of us who are called to serve with
authority in the Church, a reality that surely extends to parents with
respect to their children and teachers with respect to students. The
good news is that, by the grace of God, rehabilitation is not only
possible but likely, if we pray.
We know, from the Acts of the Apostles and from tradition, that Simon was indeed enabled by the grace of God to become the rock the Church needed. Like Jeremiah in today's First Reading, and like another initially recalcitrant instrument (Paul), Peter was soon impelled to generous service by a fire in the belly.
Paul himself, in the Second Reading (from Romans), supplies a stunning image for Christian service that deserves our attention. “Offer your bodies,” he writes, “as a living sacrifice, holy and pleasing to God, your spiritual worship.” As Jesus drew from Temple tradition to speak of building on a rock, Paul too draws from the realm of the Temple. Israel's practice had been to offer up the bodies of dead animals in Temple worship. Now Paul—in the spirit of Isaiah, Micah, and Psalm 51—says that the best offering to God is not a dead animal body but your own living one, not in suicidal immolation but in the very living out of your life. The rest of Romans (Rm 12:3ff) spells that out as building up the body of the Church by using one's gifts in mutual service, hospitality, prayer, and love of enemies.
