"My sheep hear My voice * * * and I give them everlasting life; and they shall not perish forever, and no man shall pluck them out of My hand."
The following argument, by which Christ proves that no man shall pluck His sheep from His hand, proves His consubstantiality, or the unity of His nature or essence with His Father's:
"My Father who gave Me the sheep is greater than all men or creatures (v. 29), and therefore no one can snatch the sheep or aught else from His hand. (Supreme or almighty power is here predicated of the Father.)
"Now, I and the Father are one (thing, one being), (v. 30). (Therefore, no one can snatch the sheep or aught else from My hand.)
To perceive the full meaning and strength of Jesus' argument, one must read and understand the original text of St. John's Gospel, that is, the Greek; or the Latin translation: Ego et Pater unum sumus.
If Christ had meant one in mind, or one morally, and not substantially, He would have used the masculine gender, Greek eis, (unus)—and not the neuter en, (unum)—as He did. No better interpreters of our Lord's meaning can be found than His own hearers. Had He simply declared His moral union with the Father, the Jews would not have taken up stones in protest against His making Himself God, and asserting His identity with the Father. Far from retracting His statement or correcting the Jews' impression, Jesus insists that as He is the Son of God, He has far more right to declare Himself God than the scripture had to call mere human judges gods, and He corroborates His affirmation of His physical unity with His Father by saying: 'The Father is in Me, and I am in the Father,' which evidently signifies the same as verse 30: 'I and the Father are one and the same individual being, the One God.'
The preceding argument is reinforced by John xiv:8-11: 'Philip saith to him: Lord, show us the Father. * * * Jesus saith: So long a time have I been with you and thou hast not known Me. Philip, he that seeth Me seeth the Father also. How sayest thou: Show us the Father. Do you not believe that I am in the Father and the Father in Me? The words that I speak, I speak not of Myself. But the Father Who abideth in Me, He doth the works. Believe Me that I am in the Father and the Father is in Me. What things soever the Father doth, these the Son also doth likewise. (John v:19.)
These words are a clear assertion of the physical unity of the Son and the Father. It is plain from the context that Christ means more than a physical resemblance, no matter how complete, between Him and His Father. Of mere resemblance and moral union could never be said that one is the other, and that the words uttered by one are actually spoken by the other. To see the Son and the Father at the same time in the Son, the Son and the Father must be numerically one Being. Now, Christ says: 'He that seeth the Father.' Therefore, He and the Father are numerically one Being."
3. The Holy Ghost: There remains to prove that the Holy Ghost is inseparably one with the Father and the Son. There are three who give testimony in heaven, and these three are one. (1 John v:8.) As Christ proved His identity and unity with the Father by texts quoted: 'The words that I speak, I speak not of Myself. But the Father Who abideth in Me, He doth the works,' so He now shows His unity with the Holy Ghost by almost the selfsame sentences: 'When the Spirit of Truth will have come, He will teach you all truth; for He will not speak of Himself, but He will speak whatever He will hear, and will announce to you the things to come. He will glorify Me, because He will receive of mine and announce to you: whatever the Father hath are Mine. Therefore, I said: because He will receive of Mine and announce it to you.' (John xvi:13-15.)
That the Holy Ghost is one with the Son, or Jesus, is proved also by the fact that the Christian baptism is indiscriminately called the Baptism of the Holy Ghost, the Baptism in or with the Holy Ghost and the Baptism of or in Jesus: 'He [Christ] shall baptize in the Holy Ghost and fire' (that is, the Holy Ghost acting as purifying fire) (Matthew iii:11); 'have you received the Holy Ghost? We have not so much as heard whether there be a Holy Ghost.' He said: 'In what, then [in whose name, then] were you baptized?' Who said: 'In John's baptism * * * Having the instrument of the Father? heard these things they were baptized in the name of the Lord Jesus" (Acts 2:9). All we who are baptized in Christ Jesus" (Rom. 6:3).
