It is this one Spirit who makes it possible for an infant to be regenerated . . . when that infant is brought to baptism; and it is through this one Spirit that the infant so presented is reborn. For it is not written, 'Unless a man be born again by the will of his parents' or 'by the faith of those presenting him or ministering to him,' but, 'Unless a man be born again of water and the Holy Spirit.' The water, therefore, manifesting exteriorly the sacrament of grace, and the Spirit effecting interiorly the benefit of grace, both regenerate in one Christ that man who was generated in Adam.
Saint AugustineThy word remaineth for ever, which word now appeareth unto us in the riddle of the clouds, and through the mirror of the heavens, not as it is: because that even we, though the well beloved of thy Son, yet it hath not yet appeared what we shall be. He looked through the lattice of our flesh and he spake us fair, yea, he set us on fire, and we hasten on his scent. But when he shall appear, then shall we be like him, for we shall see him as he is: as he is, Lord, will our sight be, though the time be not yet.
Saint AugustineTo abstain from sin when one can no longer sin is to be forsaken by sin, not to forsake it.
Saint AugustineNothing, therefore, happens unless the Omnipotent wills it to happen. He either permits it to happen, or He brings it about Himself.
Saint AugustineAngels are spirits, but it is not because they are spirits that they are angels. They become angels when they are sent. For the name angel refers to their office, not their nature. You ask the name of this nature, it is spirit; you ask its office, it is that of an Angel, which is a messenger.
Saint Augustine
