First, Father and Son are relatives, and must needs therefore have their relation as such: A Father begetteth, a Son is begotten.
Proof.—"Who hath ascended up into heaven, or descended? Who hath gathered the wind in his fists? Who hath bound the waters in a garment? What is his name, and what is his son's name, if thou canst tell?" (Pro 30:4).
"God so loved the world, that he gave his only begotten Son," &c.
(John 3:16).
"The Father sent the Son to be the Saviour of the world" (1 John 4:14).
Secondly, The Father then cannot be that Son he begat, nor the Son that Father that begat him, but must be distinct as such.
Proof.—"I am one that bear witness of myself, and the Father that sent me beareth witness of me" (John 8:17,18).
"I came forth from the Father, and am come into the world"; again,
"I leave the world, and go to the Father" (John 16:28).
"The Father judgeth no man, but hath committed all judgment unto the Son: That all men should honour the Son, even as they honour the Father" (John 5:22,23).
Thirdly, The Father must have worship as a Father, and the Son as a Son.
Proof.—They that worship the Father must worship him "in spirit and in truth: for the Father seeketh such to worship him" (John 4:23,24).
