Rev. Fentiman gives an introduction to the thorny subject of the ‘baptism for the dead’ (1 Cor. 15:29) and argues that it refers to the purification washing for touching dead bodies in Num. 19, which the Jews (rightly) held to be a picture of the Resurrection. R.L. Dabney, amongst others took this view, though Fentiman argues it in more detail. May this be a blessing to you in understanding Scripture better.
