The citation is from 1 Cor. iii. 8. Paul and Apollos are ὁμοούσιοι, “of one substance, nature, essence,” in so far as the definition of man can be applied to each. But the presence of Paul does not carry with it the presence of Apollos, and the existence of Paul is not bound up, save accidentally, with that of Apollos. Paul could not say, “He that hath seen me hath seen Apollos.” No human being can say that of another, even though the other be a twin and closely resembling him in appearance. The root of the difference is in the difference between the Creator and the creature, the Eternal, knowing neither beginning of life nor end of days, existing from everlasting to everlasting, and that which lives under conditions and limits of time and space.
