Then Simon himself believed also. — Endless questions have been raised as to the nature of such a faith, and the effect of such a baptism. It is probable enough that he was impressed by the signs that Philip wrought; that he felt himself in the presence of a Power above his own; that he accepted Philip’s statements as to the death and resurrection of the Christ. It was such a faith as that of which St. James speaks (James 2:14; James 2:19). If we are to use the definite language of theological science, it would be true to say that he had the fides informis, faith not preceded by repentance and not perfected by love. And baptism, in such a case, the expressed or implied conditions being absent, brought with it no new birth to a higher life. He remained still “in the gall of bitterness and the bond of iniquity” (Acts 8:23). But even for him it bore its witness of the readiness of God to forgive and to regenerate. The subsequent fulfilment of the conditions which were then absent would have quickened the potential into an actual grace, and no second baptism would have been needed to supplement the shortcomings of the first. Peter calls on him (Acts 8:22) to repent and pray for forgiveness. He does not tell him that he must be baptised again.
And wondered. — The verb is the same as that rendered “bewitched” in Acts 8:9; Acts 8:11. The tables were turned. The magician yielded to a spell mightier than his own, and was, in his turn, as one beside himself with amazement. The difference between Simon and the believing Samaritans is, in this matter, suggestive. His faith rested on outward miracles. With them the miracles did but serve to confirm a faith which rested on the “prophetic word” as spoken by the Son of Man (John 4:42).
