(Emphasis ours throughout article) Not only that but more from other christian theoligians
". . . embarrassed by the simple fact that in reality the Scriptures do not explicitly present a doctrine of the 'imminent' Trinity (even John's prologue is no such doctrine)" (The Trinity, p. 22). (Author's emphasis.)
