I have notice that when dealing with the issue of Holy Baptism, many Protestant (ie low church Protestants eg baptists, some pentecostals, etc) insist that it does not save. Then they will use an unscriptural slogan to 'prove' it. "it is an outward sign of an inward change." The slogan does not even state baptism does not regenerate necessary, it does not even try to deny that maybe this inward change was the result of baptism.
Frequently when dealing with this topic we will use our verses:
"He that believeth and is baptized, shall be saved: but he that believeth not shall be condemned."--Mark 16:16
But Peter said to them: Do penance, and be baptized every one of you in the name of Jesus Christ, for the remission of your sins: and you shall receive the gift of the Holy Ghost.--Acts 2:38
