Baptism removes Original Sin (as well as all other sin), so it is more than a certificate. Yes, after the age of reason voluntary submission does occur - First Confession, Confirmation, annual (at least) renewal of Baptismal promises. Whether a Catholic “goes with the flow” or not, their Baptism is still valid. However, if they commit mortal sin and fail to receive absolution, they will not be saved.
Mt 9:29 "Mt 9:29 "Then He touched their eyes, saying, “It shall be done to you according to your faith.” It is not enough to go with the flow. One must be remain grafted onto the vine, as begins with Baptism.
Jn 15:5-6 “I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing. If anyone does not abide in Me, he is thrown away as a branch and dries up; and they gather them, and cast them into the fire and they are burned.” Going with the flow does not produce much fruit, and can/will lead to drying pu and being cast into fire.
Yes, there is repentance at First Confession and any time someone confesses their mortal sin they make a promise to repent and “sin no more.”
Only God knows whether true repentance goes along with a confession. Some might be merely going with the flow?
What would you expect the Church to say? The Scripture says “whole households,” so that does not explicitly state infants were there. We do have evidence of the Church baptizing infants very early (2nd Century?), but that doesn’t *prove without a shadow of a doubt *it was done before. Then again, there is no evidence to the contrary.
True, no evidence either way.
Yes, it is the faith of the parents at an infant Baptism. Yes, at some point, it becomes the individuals own faith. At an adult Baptism, the parent’s faith is irrellevant.
