17 We believe also “the resurrection of the flesh,” which went before in Christ: that the body too may have hope of that which went before in its Head. The Head of the Church, Christ: the Church, the body of Christ. Our Head is risen, ascended into heaven: where the Head, there also the members. In what way the resurrection of the flesh? Lest any should chance to think it like as Lazarus's resurrection, that you may know it to be not so, it is added, “Into life everlasting.” God regenerate you! God preserve and keep you! God bring you safe unto Himself, Who is the Life Everlasting. Amen.
