So I qouted St. Ambrose’s Commentaries on Twelve of David’s Psalms,
[40. 30] “It is to Peter himself that He says, 'You are Peter, and upon this rock I will build My Church [Mt 16: 18].” Where Peter is, there is the Church. And where the Church, no death is there, but life eternal."
A Protestant responded:
Your Catholic scholar Robert Eno notes that the quote you provide where Ambrose says ‘where Peter is, the Church is’: “… says nothing at all about papal authority.” - Robert Eno, the Rise of the Papacy, pp. 83-84
I dont know who Robert Eno is but I have heard this passage from St. Ambrose qouted by hundreds of highly educated Catholic Apologists, so can anyone provide more of the Commentaries on Twelve of Davids Psalms (the parts before and after it, so I can make sure I am in context) I cannot find the full work online anywhere.
