This is an assumption on your part. And it's false. The ritual of Baptism includes a profession of faith--the Apostles' Creed, as well as the Baptismal Promises.
Actually a confession of faith in the atonement of the blood of Christ is not required by Rome for a baptism which makes one a recipient of the Holy Spirit and a child of God.
Nor can it be shown that those who have received Cath. baptism manifest greater (if any) evidences of regeneration than those who realized evangelical baptism overall.
Which proves that Catholics are not Protestants.
What a bombshell!
I don’t understand why you persist in asserting that Catholics do not make a profession of faith in the atonement.
The recitation of the Nicene Creed or the Apostles’ Creed is part of the Mass, and part of the Baptism ritual. The Mass is all about the atonement accomplished in the suffering and death of Jesus. Since the atonement is part of the Catholic Faith, it is affirmed every time a Catholic professes the Faith, sometimes in words, sometimes in an ACTION.
The reception of Communion is an act which signifies PRECISELY belief in, and a determination to be joined with, the sacrificial suffering and death of Jesus.
