The Lord was Baptized, not to be cleansed Himself, but to cleanse the waters, so that those waters, cleansed by the flesh of Christ which knew no sin, might have the power of Baptism.
AmbroseIf every time the blood is poured out it is poured out for the remission of sins, I ought to receive it always, that my sins may always be forgiven me.
Ambrose... the Lord Jesus said, 'To those who are in bonds, Come out, and to those who are in prison, Go forth' (Isa. 49:9); so your sins are forgiven. All, then, are forgiven, nor is there any one whom He has not loosed. For thus it is written, that He has forgiven 'all transgressions, doing away with the handwriting of the ordinance that was against us' (Col. 2:13-14). Why, then, do we hold the bonds of others, while we enjoy our own remission? He, who forgave all, required of all that what every one remembers to have been forgiven to himself, he also should forgive others.
