He did say that even though others may have true Sacraments, they are of no avail. *That gave me pause. * It also contradicts the Church’s teaching on the validity of Protestant baptism.
What you heard was the Priest* quoting *St. Augustine, Father and Doctor of the Universal Church, that gave you pause. Here’s the quote:
**St. Augustine (354-430): **"*No man can find salvation except in the Catholic Church. *Outside the Catholic Church one can have everything except salvation. One can have honor,
one can have sacraments, one can sing alleluia, one can answer amen, one can have faith in the Name of the Father and the Son and of the Holy Ghost, and preach it too,
but never can one find salvation except in the Catholic Church."
Regarding your comment about Protestants being able to confer a valid baptsim, which you said was contrary to what St. Augustine said, we have to keep the following in mind: Since the
Catholic sacrament of baptism can be performed by anyone (a heretic, an infidel, etc.), it is possible for a Protestant to confer it validly. However, when a heretic
receives baptism - even a valid baptism -
he does not receive it unto salvation. The baptism might be valid,
but a heretic does not receive grace through that valid sacrament. Why? Because right faith is necessary a person above the age of reason to receive grace through baptism. Right faith is not necessary to receive the sacrament validly, but it is necessary to receive grace through the sacrament. Let me explain…
Baptism produces a two-fold effect: It prints an indelible character upon the soul, and infuses sanctifying grace. When a heretic receives a valid baptism, he receives the character,
but not sanctifying grace. Why? Because right faith is necessary for a person to receive sanctifying grace.
**St. Thomas: Whether faith is required on the part of the one baptized: **
I answer that, As appears from what has been said above (63, 6; 66, 9) Baptism produces a twofold effect in the soul, viz. the character and grace. Therefore in two ways may a thing be necessary for Baptism. First, as something without which grace, which is the ultimate effect of the sacrament, cannot be had. And thus right faith is necessary for Baptism, because, as it appears from Romans 3:22, the justice of God is by faith of Jesus Christ.
Secondly, something is required of necessity for Baptism, because without it the baptismal character cannot be imprinted And thus right faith is not necessary in the one baptized any more than in the one who baptizes: provided the other conditions are fulfilled which are essential to the sacrament. For the sacrament is not perfected by the righteousness of the minister or of the recipient of Baptism, but by the power of God.
Reply to Objection 1. Our Lord is speaking there of Baptism as bringing us to salvation by giving us
sanctifying grace: which of course cannot be without right faith: wherefore He says pointedly: “He that believeth and is baptized, shall be saved.”

So, right faith is
not necessary for baptism to be valid and produce the character;
but right faith is necessary for baptism to give grace - and it is grace, not the character, that saves.
Now, it is possible for a person to be baptized outside of the Church (by a Protestant minister, for example) and not be in obstinate denial of a dogma. In this case (and God alone can judge such things), the person would receive both the character and sanctifying grace through baptism.
We hear a lot today about the “common baptism” we have with various non-Catholic sects, but we do not also share a common faith (the Catholic faith) the common baptism we share with those outside the Church wil not benefit them. Without right faith, baptism will not save anyone.
