"He that seeketh His glory that sent Him, the same is true" (vii. 18).
"I am from Him, and He hath sent me" (vii. 29).
"I do nothing of myself, but as my Father hath taught me, I speak these things" (viii. 28).
"Neither came I of myself, but He sent me" (viii. 42).
"I have power to take it [my life] again; this commandment have I received of my Father" (x. 18).
"My Father, which gave them me, is greater than all" (x. 29).
"I have kept my Father's commandments, and abide in His love" (xv. 10).
I have read Justin carefully for the purpose of marking every expression in his writings bearing upon the relations of the Son to the Father, and I find none so strongly expressing subordination as these, and the declarations of this kind in the works of Justin are nothing like so numerous as they are in the short Gospel of St. John.
The reader who knows anything about the history of Christian doctrine will see at a glance how impossible it would have been for a Gospel ascribing these expressions to Jesus to have been received by the Christian Church long before Justin's time, except that Gospel had been fully authenticated as the work of the last surviving Apostle.
