Good pick up AveMaria. This is unabashed, full throttle, Christian doctrine. It is almost courageous, in this ecumenical and PC era that the pope would reiterate these truths.
Only last week the gospel reading from John concerned Christ's final prayer before his arrest. He prayed for unity. It was Christ's wish that all believers be one, "as you Father are in me, and I in you; I pray that they may be one in us." The homilist posed the question, " Are Christians as one?" No, came the reply, and he laid the blame on Satan. Just as Satan used scripture to tempt the Christ, Satan has used scripture to divide the community of believers.
It is wonderful to hear the pope rallying the Church behind the chair of Peter, just as Cyprian did over 1700 years ago. God bless Pope Benedict.
