John Lightfoot on Matthew 18:18

[Whatsoever ye shall bind on earth, &c.] These words depend upon the former. He had been speaking concerning being loosed from the office of a brother in a particular case: now he speaks of the authority and power of the apostles of loosing and binding "any thing" whatsoever seemed them good, being guided in all things by the Holy Ghost. We have explained the sense of this phrase at chapter 16; and he gives the same authority in respect of this, to all the apostles here, as he did to Peter there; who were all to be partakers of the same Spirit and of the same gifts.

This power was built upon that noble and most self-sufficient foundation, John 16:13, "The Spirit of truth shall lead you into all truth." There lies an emphasis in those words, "into all truth." I deny that any one, any where, at any time, was led, or to be led, into all truth, from the ascension of Christ, unto the world's end, beside the apostles. Every holy man, certainly, is led into all truth necessary to him for salvation: but the apostles were led into all truth necessary both for themselves and the whole church; because they were to deliver a rule of faith and manners to the whole church throughout all ages. Hence, whatsoever they should confirm in the law was to be confirmed; whatsoever they should abolish was to be abolished: since they were endowed, as to all things, with a spirit of infallibility, guiding them by the hand into all truth.
