Insomuch that they brought forth the sick - This verse is a continuation of the subject begun in the 12th. The following is the order in which all these verses should be read, from the 11th to the 15th.

Acts 5:11. And great fear came upon all the Church, and upon as many as heard these things.

Acts 5:13. And of the rest durst no man join himself to them; but the people magnified them:

Acts 5:14. And believers were the more added to the Lord, both men and women.

Acts 5:12. (last clause.) And they were all with one accord in Solomon's porch.

Acts 5:12. (first clause.) And by the hands of the apostles were many signs and wonders wrought among the people;

Acts 5:15. Insomuch that they brought forth the sick into the streets, and laid them on beds and couches, etc., etc.

How these different verses and clauses of verses, got so intermingled and confounded as they are now in our common text, I cannot tell; but the above will appear at once to be the natural order in which they should be placed.

That - the shadow of Peter passing by - I cannot see all the miraculous influence here that others profess to see. The people who had seen the miracles wrought by the apostles pressed with their sick to share the healing benefit: as there must have been many diseased people, it is not likely that the apostles, who generally addressed such persons, prayed and used imposition of hands, could reach all those that were brought to them, as fast as the solicitude of their friends could wish. As, therefore, they could not get Peter or the other apostles, personally, to all their sick, they thought if they placed them on that side of the way where the shadow was projected, (the sun probably now declining, and consequently the shadow lengthening), they should be healed by the shadow of the man passing over them, in whose person such miraculous powers were lodged. But it does not appear that the persons who thus thought and acted were of the number of those converts already made to the faith of Christ; nor does it appear that any person was healed in this way. The sacred penman simply relates the impression made on the people's minds; and how they acted in consequence of this impression. A popish writer, assuming that the shadow of Peter actually cured all on which it was projected, argues from this precarious principle in favor of the wonderful efficacy of relics! For, says he, "if the shadow of a saint can do so much, how much more may his bones, or any thing that was in contact with his person, perform!" Now, before this conclusion can be valid, it must be proved:

1. That the shadow of Peter did actually cure the sick;

2. That this was a virtue common to all the apostles;

3. That all eminent saints possess the same virtue;

4. That the bones, etc., of the dead, possess the same virtue with the shadow of the living;

5. That those whom they term saints were actually such;

Gamaliel's Counsel
'Refrain from these men, and let them alone; for if this counsel or this work be of men, it will come to nought: 39. But if it be of God, ye cannot overthrow it; lest haply ye be found even to fight against God.'--ACTS v. 38, 39. The little that is known of Gamaliel seems to indicate just such a man as would be likely to have given the advice in the text. His was a character which, on its good side and by its admirers, would be described as prudent, wise, cautious and calm, tolerant, opposed to fanaticism …

Whether Whatever God Does Outside the Natural Order is Miraculous?
Objection 1: It would seem that not everything which God does outside the natural order of things, is miraculous. For the creation of the world, and of souls, and the justification of the unrighteous, are done by God outside the natural order; as not being accomplished by the action of any natural cause. Yet these things are not called miracles. Therefore not everything that God does outside the natural order is a miracle. Objection 2: Further, a miracle is "something difficult, which seldom occurs, …

Whether Subjects are Bound to Obey their Superiors in all Things?
Objection 1: It seems that subjects are bound to obey their superiors in all things. For the Apostle says (Col. 3:20): "Children, obey your parents in all things," and farther on (Col. 3:22): "Servants, obey in all things your masters according to the flesh." Therefore in like manner other subjects are bound to obey their superiors in all things. Objection 2: Further, superiors stand between God and their subjects, according to Dt. 5:5, "I was the mediator and stood between the Lord and you at that …
