16 And immediately, then, after the judgment mentioned, all which the Father, not judging any man, has given to the Son, what shall be? What follows? “That all may honor the Son, even as they honor the Father.” The Jews honor the Father, despise the Son. For the Son was seen as a servant, the Father was honored as God. But the Son will appear equal with the Father, that all may honor the Son, even as they honor the Father. This we have, therefore, now in faith. Let not the Jew say, “I honor the Father; what have I to do with the Son?” Let him be answered, “He that honors not the Son, honors not the Father. Thou liest every way; you blaspheme the Son, and dost wrong to the Father. For the Father sent the Son, and you despise Him whom the Father sent. How can you honor the sender, who blaspheme the sent?”
