Hebrews 3:1

1.Wherefore, holy brethren, etc. He concludes the preceding doctrine with a necessary exhortation, that the Jews should attentively consider what sort of being and how great Christ is. As he had before, by naming him a teacher and a priest, briefly compared him with Moses and Aaron, so he now includes both clauses; for he adorns him with two titles, as he sustains a twofold character in the Church of God. Moses was a prophet and a teacher, and Aaron was a priest; but the two offices belong to Christ. If then we seek rightly to know him, we must inquire what sort of being he is; yea, he must be clothed with his own power, lest we lay hold on an empty shadow and not on him. (53)

First, the word consider, is important, for it intimates that singular attention is required, as he cannot be disregarded with impunity, and that at the same time the true knowledge of Christ is sufficient to dissipate the darkness of all errors. And to encourage them the more to pursue this study, he reminds them of their calling; as though he had said, “God favored you with no common grace when He called you into his kingdom; (54) it now remains that you have your eyes fixed on Christ as your leader in the way.” (55) For the calling of the godly cannot be otherwise confirmed than by a thorough surrender of themselves to Christ. We ought not therefore to regard this as said only to the Jews, but that it is a general truth addressed to all who desire to come into the kingdom of God; they ought sedulously to attend to Christ, for he is the sole instructor of our faith, and has confirmed it by the sacrifice of himself; for confession, or profession, is to be taken here for faith, as thought he had said, that the faith we profess is vain and of no avail, unless Christ be its object. (56)

He had before exalted Christ as a teacher above all the prophets, including no doubt Moses among the rest; but here refers to Moses as the leader of the people, as one sent especially by God to conduct them from Egypt through the wilderness to the land of Canaan. But as our call is from heaven and to heaven, Christ is sent as a messenger to lead us to the heavenly country. We hence see that in this connection the “heavenly calling” is to be taken most suitably as a call to heaven. — Ed.
