Charles Ellicott Commentary Acts 10:43

"To him bear all the prophets witness, that through his name every one that believeth on him shall receive remission of sins." — Acts 10:43 (ASV)

To him give all the prophets witness.—As in Saint Peter’s earlier speeches in Acts 2:3, so here we trace the result of our Lord’s teaching, given in the interval between the Resurrection and Ascension, concerning the method of prophetic interpretation which discerns, below all temporary and historical references, the undercurrent of testimony to the kingdom of which Christ was the Head.

That through his name. . . .—We can easily imagine the impression these words must have made on the anxious listeners. This was the answer to their doubts and perplexities. Not by submitting to the bondage of the Law, nor by circumcision and all that it implied, but by the simple act of faith in Christ and in the power of His Name—i.e., of all the attributes and energies of which the Name was the symbol—they, Gentiles as they were, might receive that remission of sins. Their conscience, now roused to its full activity, taught them that this remission was the indispensable condition of acceptance and of peace. The intensity of that emotion, the satisfaction of all their previous yearnings, placed them subjectively in a spiritual condition which prepared the way for the wonder which the next verse narrates.
