Catholics are often challenged with the question, “Why do we baptize infants?
The answer is, “To give them Life: Eternal Life.” We also have Jesus’ commandment to his disciples,
“Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded you.”
Mat 28:19-20
By “All nations” Jesus means everyone (Not just adults).
