Claiming that Catholic baptism causes an infant to receive the Holy Spirit is a huge assertion. Can you prove it through the same Scriptures you are claiming Catholicism interprets?
As an old Belgian monk once taught us, God loves the family, which He created, so much that He allows the family to participate in the bringing into existence out of nothingness the human; both body and soul. This is a profound mystery. God is the Creator, and we participate in His creating.
Similarly, the family is given the greatest gift in that God allows the parents to participate in His gift-giving with regard to the gift of Faith.
