Galatians 1:2

2.And all the brethren who are with me. — He appears to have usually written in the name of many persons, judging that, if those to whom he wrote should attach less weight to a solitary individual, they might listen to a greater number, and would not despise a whole congregation. His general practice is, to insert the salutations from brethren at the conclusion, instead of introducing them at the commencement as joint authors of the epistle: at least, he never mentions more than two names, and those very well known. But here he includes all the brethren; and thus adopts, though not without good reason, an opposite method. The concurrence of so many godly persons must have had some degree of influence in softening the minds of the Galatians, and preparing them to receive instruction.

To the churches of Galatia. It was an extensive country, and therefore contained many churches scattered through it. But is it not wonderful that the term “Church”, which always implies unity of faith, should have been applied to the Galatians, who had almost entirely revolted from Christ? I reply, so long as they professed Christianity, worshipped one God, observed the sacraments, and enjoyed some kind of Gospel ministry, they retained the external marks of a church. We do not always find in churches such a measure of purity as might be desired. The purest have their blemishes; and some are marked, not by a few spots, but by general deformity. Though the doctrines and practices of any society may not, in all respects, meet our wishes, we must not instantly pronounce its defects to be a sufficient reason for withholding from it the appellation of a Church. Paul manifests here a gentleness of disposition utterly at variance with such a course. Yet our acknowledgment of societies to be churches of Christ must be accompanied by an explicit condemnation of everything in them that is improper or defective; for we must not imagine, that, wherever there is some kind of church, everything in it that ought to be desired in a church is perfect.

I make this observation, because the Papists, seizing on the single word Church, think that whatever they choose to force upon us is sanctioned; though the condition and aspect of the Church of Rome are widely different from what existed in Galatia. If Paul were alive at the present day, he would perceive the miserable and dreadfully shattered remains of a church; but he would perceive no building. In short, the word Church is often applied by a figure of speech in which a part is taken for the whole, to any portion of the church, even though it may not fully answer to the name.
