"O Lord,"
does not administer Baptism, but rather he who, with the Name, also has the right faith ...
There are many other heresies, too, which use the words only, but not in a right sense, nor with sound faith, and in consequence the water which they pour is unprofitable,
deficient in piety, so that he who is sprinkled by them is polluted rather than redeemed.
- St. Athanasius
Although among heretics and schismatics there is the same Baptism, nevertheless,
the remission of sins is not operative among them because of the very rottenness of discord and wickedness of dissension ...
Baptism was in them, but it did not profit them outside the Church ...
Outside the Church, Baptism works death because of discord.
- St. Augustine
Whereas there can be but one Baptism, they think they can Baptize;
they have abandoned the fountain of life, yet promise the life and grace of the waters of salvation.
It is not cleansing which men find there, but soiling;
their sins are not washed away, but only added to.
That being "born again"
does not bring forth sons to God but to the Devil.
Born of a lie, they cannot inherit the things which Truth has promised;
begotten by the faithless, they are deprived of the grace of faith.
- St. Cyprian
A person may be Baptized, and yet not born again to grace, in consequence of not having the necessary dispositions at Baptism.
- St. Alphonsus Maria Liguori
