Matthew Henry on Acts 11:25-30

Hitherto the followers of Christ were called disciples, that is, learners, scholars; but from that time they were called Christians. The proper meaning of this name is, a follower of Christ; it denotes one who, from serious thought, embraces the religion of Christ, believes his promises, and makes it his chief care to shape his life by Christ's precepts and example. Hence it is plain that multitudes take the name of Christian to whom it does not rightly belong. But the name without the reality will only add to our guilt. While the bare profession will bestow neither profit nor delight, the possession of it will give both the promise of the life that now is, and of that which is to come. Grant, Lord, that Christians may forget other names and distinctions, and love one another as the followers of Christ ought to do. True Christians will feel for their brethren under afflictions. Thus will fruit be brought forth to the praise and glory of God. If all mankind were true Christians, how cheerfully would they help one another! The whole earth would be like one large family, every member of which would strive to be dutiful and kind.
