Water Baptism.. to those who believed it is a requirements for salvation. What is the difference if you are baptize in the name of trinity(Father,Son,and H.S) than in the name of Jesus Christ only? or even to those that believe that water baptism is an act of obedience only (shadow/mirror/ordinance/sacraments) .. Ref verse Matthew 28:19 and Act 2:38 kindly answer with thoughtfulness.
