Knowing, as he did, from the inspired prophecies of his Father’s Word that there would be rebellious apostates from the true Christian faith and service, Jesus quite properly raised this searching question that affects each disciple of his. But, by the form of his question, was he speaking about a particular man, an individual disciple of his? Or was he speaking with reference to a class of disciples? The Critical and Exegetical Hand-Book to the Gospel of Matthew, by H. A. W. Meyer, Th.D., (1884) makes a suggestion. On page 429, it says regarding the expression “who therefore” (AV): “Considering the necessity for preparedness thus indicated. The inference itself is presented in the form of an allegory, the doúlos [slave] representing the disciples whom the Lord has appointed to be the guides of His church, in which they are required to show themselves faithful (1 Cor. iv. 1 f.) and prudent, . . . ” This limiting the “slave” to the twelve apostles, however, might allow for the doctrine of an apostolic succession or an episcopal succession, a succession of bishops (overseers) by the religious process of ordination.

Regarding Matthew 11:12, German scholar Heinrich Meyer states: “In this way is described that eager, irresistible striving and struggling after the approaching Messianic kingdom . . . So eager and energetic (no longer calm and expectant) is the interest in regard to the kingdom. The [bi·a·stai′] are, accordingly, believers [not enemy attackers] struggling hard for its possession.”—Meyer’s Critical and Exegetical Hand-Book to the Gospel of Matthew, 1884, p. 225
