If you want to quote Justin we can do that.

"For Isaiah did not send you to a bath, there to wash away murder and other sins, which not even all the water of the sea were sufficient to purge;

but, as might have been expected, this was that saving bath of the olden time which followed s those who repented, and who no longer were purified by the blood of goats and of sheep,

or by the ashes of an heifer, or by the offerings of fine flour,

but by faith through the blood of Christ, and through His death, who died for this very reason, as Isaiah himself said, when he spake thus: 'The Lord shall make bare His holy arm in the eyes of all the nations, and all the nations and the ends of the earth shall see the salvation of God.

The Didache is not much help for the Roman Catholic either:

We thank Thee, holy Father, for Thy holy name which You didst cause to tabernacle in our hearts, and for the knowledge and faith and immortality, which You modest known to us through Jesus Thy Servant; to Thee be the glory for ever. Thou, Master almighty, didst create all things for Thy name's sake; You gavest food and drink to men for enjoyment, that they might give thanks to Thee;

but to us You didst freely give spiritual food and drink and life eternal through Thy Servant.

By some accounts this pre-dates Justin.
