The Second Man

Dictionary of Biblical Words:

This expression is used of Christ as the head of a new and heavenly people. In this sense there are but two men, Adam the first, and Christ the second, and to one of these two every human being belongs. All by nature stand in Adam, and those who accept grace in Christ. The name, “second man” suggests many comparisons, or rather contrasts, between the history of Adam and of Christ, which are most interesting.

See ADAM, THE LAST.
