1 Pet. 3:18. For Christ also died for sins once for all,
the just for
the unjust, so that He might bring us to God, having been put to death in the flesh, but made alive in the spirit;
19. in which also He went and made proclamation to the spirits
now in prison,
20. who once were disobedient, when the patience of God kept waiting in the days of Noah, during the construction of the ark, in which a few, that is, eight persons, were brought safely through
the water.
21. Corresponding to that, baptism now saves you--not the removal of dirt from the flesh, but an appeal to God for a good conscience—through the resurrection of Jesus Christ,
22. who is at the right hand of God, having gone into heaven, after angels and authorities and powers had been subjected to Him. (NASB, 1995)
These verses, as they have come down to us, expressly teach baptismal regeneration. “Eight persons were brought safely through the water. Corresponding to that,
baptism now saves you.” Water baptism does not save you by removing dirt from the flesh, but by the appeal that it expresses to God “for a good conscience—through the resurrection of Jesus Christ, who is at the right hand of God, having gone into heaven, after angels and authorities and powers had been subjected to Him.”
Those Baptist who take exception to this passage of Scripture and mutilate it to fit their private interpretation of the Bible might want to consider that unless 1 Per. 3:18-22 has not come down to us accurately, or is not inspired Scripture, they are mutilating the words of God. Personally, I do not know for sure what the case is here, but this passages as we have it expressly teaches Baptismal Regeneration, and to condemn Christians who believe this passage in the Bible is to condemn Christians for choosing to Believe the Bible. If that is not another Gospel . . . .
May I suggest that you carefully and prayerfully read Mat_28:19; Mar_16:16; Act_2:38, Act_22:16; Rom_6:3-6; 1Co_12:13; Gal_3:27; Eph_5:26; Col_2:12; and Tit_3:5-7 in the light of 1 Pet.3:18-22 and see if you find any contradictions, or perhaps support for 1 Pet.3:18-22 as it has come down to us.
