St. Paul uses the word also in his epistle to the Ephesians, the first chapter, the fifth verse. 'Having predestinated us unto the adoption of children by Jesus Christ to himself,' says the authorized version; 'Having foreordained us unto adoption as sons through Jesus Christ unto himself,' says the revised--and I see little to choose between them: neither gives the meaning of St. Paul. If there is anything gained by the addition of the words 'of children' in the one case, and 'as sons' in the other, to translate the word for which 'adoption' alone is made to serve in the other passages, the advantage is only to the minus-side, to that of the wrong interpretation.
Children we were; true sons we could never be, save through The Son. He brothers us. He takes us to the knees of the Father, beholding whose face we grow sons indeed. Never could we have known the heart of the Father, never felt it possible to love him as sons, but for him who cast himself into the gulf that yawned between us. In and through him we were foreordained to the sonship: sonship, even had we never sinned, never could we reach without him. We should have been little children loving the Father indeed, but children far from the sonhood that understands and adores. 'For as many as are led by the spirit of God, these are sons of God;' 'If any man hath not the spirit of Christ, he is none of his;' yea, if we have not each other's spirits, we do not belong to each other. There is no unity but having the same spirit. There is but one spirit, that of truth.
It remains to note yet another passage.
That never in anything he wrote was it St. Paul's intention to contribute towards a system of theology, it were easy to show: one sign of the fact is, that he does not hesitate to use this word he has perhaps himself made, in different, and apparently opposing, though by no means contradictory senses: his meanings always vivify each other. His ideas are so large that they tax his utterance and make him strain the use of words, but there is no danger to the honest heart, which alone he regards, of misunderstanding them, though 'the ignorant and unsteadfast wrest them' yet. At one time he speaks of the sonship as being the possession of the Israelite, at another as his who has learned to cry _Abba, Father_; and here, in the passage I have now last to consider, that from the 18th to the 25th verse of this same eighth chapter of his epistle to the Romans, he speaks of the _niothesia_ as yet to come--and as if it had to do, not with our spiritual, but our bodily condition. This use of the word, however, though not the same use as we find anywhere else, is nevertheless entirely consistent with his other uses of it.
The 23rd verse says, 'And not only so, but ourselves also, which have the first fruits of the spirit, even we ourselves groan within ourselves, waiting for adoption, the redemption of our body.'
It is nowise difficult to discern that the ideas in this and the main use are necessarily associated and more than consistent. The putting of a son in his true, his foreordained place, has outward relations as well as inward reality; the outward depends on the inward, arises from it, and reveals it. When the child whose condition under tutors had passed away, took his position as a son, he would naturally change his dress and modes of life: when God's children cease to be slaves doing right from law and duty, and become his sons doing right from the essential love of God and their neighbour, they too must change the garments of their slavery for the robes of liberty, lay aside the body of this death, and appear in bodies like that of Christ, with whom they inherit of the Father. But many children who have learned to cry _Abba, Father_, are yet far from the liberty of the sons of God. Sons they are and no longer children, yet they groan as being still in bondage!-- Plainly the apostle has no thought of working out an idea; with burning heart he is writing a letter: he gives, nevertheless, lines plentifully sufficient for us to work out his idea, and this is how it takes clear shape:--
