Not sure what your reaction is a frowning face to the patristic teaching. Any bolding is mine.
"Just as baptism is of no profit to the man who renounces the world in words and not in deeds, so it is of
no profit to him who is baptized in heresy or schism; but each of them, when he amends his ways, begins to receive profit from that which before was not profitable, but was yet already in him. "- St. Augustine, on Baptism against the Donatists.
We command that a bishop, or presbyter, or deacon who receives the baptism, or the sacrifice of heretics, be deprived:
For what agreement is there between Christ and Belial? Or what part has a believer with an infidel? - Apostolic Canon 46
Anyone who receives the sacrament of Baptism, whether in the Catholic Church or in a heretical or schismatic one, receives the whole Sacrament; but salvation, which is the strength of the Sacrament,
he will not have, if he has had the sacrament outside the Catholic Church. He must, therefore, return to the Church, not to that he might receive again the sacrament of Baptism, which no one dare repeat in any baptized person, but so that he may receive eternal life in Catholic society, for the obtaining of which no one is suited who, even with the Sacrament of Baptism, remains estranged from the Catholic Church.”- St. Fulgebtius of Ruspe
"Certainly a heretic has the baptism of Christ but, because he is outside the unity of the faith, it produces
nothing for him."St. Isidore of Seville
Canon 57 of Carthage: For in coming to faith they thought the true Church to be their own and there they believed in Christ, and received the sacraments of the Trinity. And that all these sacraments are altogether true and holy and divine is most certain, and in them the whole hope of the soul is placed, although the presumptuous audacity of heretics, taking to itself the name of the truth, dares to administer them. They are but one after all, as the blessed Apostle tells us, saying: One God, one faith, one baptism, and it is not lawful to reiterate what once only ought to be administered. Those having been baptized having anathematized their error may be received by the imposition of the hand into the one Church, the pillar as it is called, and the one mother of all Christians, where all these Sacraments are received unto salvation and everlasting life;
even the same sacraments which obtain for those persevering in heresy the heavy penalty of damnation."
