5:16. Confess therefore your sins one to another: and pray one for another, that you may be saved. For the continual prayer of a just man availeth much.
Confess your sins one to another… That is, to the priests of the church, whom (ver.14) he had ordered to be called for, and brought in to the sick; moreover, to confess to persons who had no power to forgive sins, would be useless. Hence the precept here means, that we must confess to men whom God hath appointed, and who, by their ordination and jurisdiction, have received the power of remitting sins in his name.
5:17. Elias was a man passible like unto us: and with prayer he prayed that it might not rain upon the earth. And it rained not for three years and six months.
5:18. And he prayed again. And the heaven gave rain: and the earth brought forth her fruit.
5:19. My brethren, if any of you err from the truth and one convert him:
5:20. He must know that he who causeth a sinner to be converted from the error of his way shall save his soul from death and shall cover a multitude of sins.
