Baptism is a something Jesus commanded his followers to do, as He did when He was baptized by John the Baptist “to fulfill all righteousness”. It is a ceremony entered into with forethought and deliberation, after making an informed decision to repent of our sins and accept Jesus Christ as our Redeemer, Lord and Savior and to obey and follow Him—a decision no infant is capable of making. Matthew 28:18-20 “Then Jesus came to them and said, “All authority in heaven and on earth has been given to Me. Therefore go and make disciples of all nations, baptizing them in the name of the Father and of the Son, and of the Holy Spirit, and teaching them to obey all that I have commanded you. And surely I am with you always, to the very end of the age.”
Aside from the fact that it is not biblical, infant baptism can lead to child abuse, as this video of a priest in France slapping a baby who is crying evidences. Now many babies getting water dribbled on them might be likely to cry, but most spiritual leaders are not in the habit of striking them and holding their faces until they scream and their frantic parent has to snatch them away. It was reported that after this video went viral, the priest was suspended.
