51 Cf. Saint Ambrose, De Sacramentis, IV, 6, 28: PL 16, 464: “I must receive it always, so that it may always forgive my sins. If I sin continually, I must always have a remedy”; ID., op. cit., IV, 5, 24: PL 16, 463: “Those who ate manna died; those who eat this body will obtain the forgiveness of their sins”; Saint Cyril of Alexandria, In Joh. Evang., IV, 2: PG 73, 584-585: “I examined myself and I found myself unworthy. To those who speak thus I say: when will you be worthy? When at last you present yourself before Christ? And if your sins prevent you from drawing nigh, and you never cease to fall – for, as the Psalm says, ‘what man knows his faults?’ – will you remain without partaking of the sanctification that gives life for eternity?”
