But though we, or an angel from heaven, preach any other gospel to you than that which we have preached to you, let him be accursed.…
There are divers improvements and modifications of the same truth, according to the various gifts and abilities which God communicates to His servants, some in one kind, and some in another. Ye shall have some kind of persons who would confine all kind of preachers to one and the same kind of way and method of preaching. This is a business which is not to be expected, neither does the apostle urge it in this Scripture, but in the allowing to every one that gift and manner of preaching which is most agreeable to himself (so it be grave and sober, and proper, and becoming the majesty of the gospel), he does limit them only for matter to the doctrine of the Scripture; that there be nothing delivered but 'what does consist with that, and which either directly or by consequent is to be found in it.
(T. Horton, D. D.)
