No, it does not.
Augustine did not promote new ideas, he developed what was already there (Titus 3:5-7) because the consistent and unanimous teachings on baptism was challenged by heretics. As a side note, Luther taught baptismal regeneration, Calvin denied it. Protestantism is hopelessly divided into 5 major camps on baptism.
“And if any one seek for divine authority in this matter, though what is held by the whole Church, and that not as instituted by Councils, but as a matter of invariable custom, is rightly held to have been handed down by apostolical authority, still we can form a true conjecture of the value of the sacrament of baptism in the case of infants, from the parallel of circumcision, which was received by God’s earlier people, and before receiving which Abraham was justified, as Cornelius also was enriched with the gift of the Holy Spirit before he was baptized.”
Augustine, On Baptism against the Donatist, 4:24:31 (A.D. 400).
“The blessed Cyprian, indeed, said, in order to correct those who thought that an infant should not be baptized before the eighth day, that it was not the body but the soul which behoved to be saved from perdition — in which statement he was not inventing any new doctrine, but preserving the firmly established faith of the Church; and he, along with some of his colleagues in the episcopal office, held that a child may be properly baptized immediately after its birth.”
Augustine, Epistle 166:8:23 (A.D. 412).
“This grace, however, of Christ, without which neither infants nor adults can be saved, is not rendered for any merits, but is given gratis, on account of which it is also called grace. ‘Being justified,’ says the apostle, ‘freely through His blood.’ Whence they, who are not liberated through grace, either because they are not yet able to hear, or because they are unwilling to obey; or again because they did not receive, at the time when they were unable on account of youth to hear, that bath of regeneration, which they might have received and through which they might have been saved, are indeed justly condemned; because they are not without sin, either that which they have derived from their birth, or that which they have added from their own misconduct. ‘For all have sinned’–whether in Adam or in themselves–“and come short of the glory of God.'”
Augustine, On Nature and Grace, 4 (A.D. 415).
SACRAMENT OF BAPTISM - Scripture Catholic
The Catholic Church holds that there was one apostolic deposit, given by Jesus Christ to the apostles, and that there has been
no essential change in that. The Catholic Church preserves this apostolic deposit (
Jude 3), and is the Guardian of it. But, on the other hand, there is a growth in clarity of those truths, and men's
understanding increases. One must keep this distinction in mind when discussing development.
