Today is the 41st anniversary of my baptism!
Christ taught us that to enter heaven, we must be “born again of water and the Spirit” (John 3:5) – a statement that from the earliest days of the Church have been understood to refer to baptism. St. Peter taught that “baptism…now saves you” (1 Peter 3:21), and St. Paul wrote that God “saved us…by the washing of regeneration and renewal in the Holy Spirit” (Titus 3:5). So, when I was baptized 41 years ago, I was “born again” the Bible way!
I was four months old when I was baptized. The Methodist congregation our family attended shared the same belief in infant baptism that is practiced in the Catholic Church. In fact, most non-Catholic groups also practice infant baptism – Orthodox, Lutheran, Reformed/Presbyterian, Anglican/Episcopal, Methodist and more. Infant baptism is not followed by some Protestant groups, in particular those that stem from the Anabaptist movement that came later in Reformation history.
Interested in learning why we baptize infants? Here are two helpful articles from Catholic Answers and Steve Ray (in addition to his blog post, which is about baptism in general, read the PDF of his article on infant baptism which he links to in one of the comments).
