Is Christ God?

This name was not given to Christ in consequence of some great achievement, but it is His by right of inheritance. Speaking of the power and greatness of Christ, the writer to the Hebrews says that He is made so much better than the angels, because "He hath by inheritance obtained a more excellent name than they." Heb. 1:4. A son always rightfully takes the name of the father; and Christ, as "the only begotten Son of God," has rightfully the same name. A son, also, is, to a greater or less degree, a reproduction of the father; he has to some extent the features and personal characteristics of his father; not perfectly, because there is no perfect reproduction among mankind. But there is no imperfection in God, or in any of His works, and so Christ is the "express image" of the Father's person. Heb. 1:3. As the Son of the self- existent God, He has by nature all the attributes of Deity.
It is true that there are many sons of God, but Christ is the "only begotten Son of God," and therefore the Son of God in a sense in which no other being ever was or ever can be. The angels are sons of God, as was Adam (Job 38:7; Luke 3:38), by creation; Christians are the sons of God by adoption (Rom. 8:14, 15), but Christ is the Son of God by birth. The writer to the Hebrews further shows that the position of the Son of God is not one to which Christ has been elevated, but that it is one which He has by right.” Ellet J. Waggoner,  Christ And His Righteousness, pp. 9-10, 1890 

Let the pioneers speak through the reprinting of their writings

“God has given me light regarding our periodicals. What is it?—He has said that the dead are to speak. How?—Their works shall follow them. We are to repeat the words of the pioneers in our work, who knew what it cost to search for the truth as for hidden treasure, and who labored to lay the foundation of our work. They moved forward step by step under the influence of the Spirit of God. One by one these pioneers are passing away. The word given me is, Let that which these men have written in the past be reproduced.”

“A few are still alive who passed through the experience gained in the establishment of this truth. God has graciously spared their lives to repeat and repeat till the close of their lives, the experience through which they passed even as did John the apostle till the very close of his life. And the standard-bearers who have fallen in death, are to speak through the reprinting of their writings. I am instructed that thus their voices are to be heard. They are to bear their testimony as to what constitutes the truth for this time.”   Counsels to Writers and Editors pp. 28, 32.

They who have read our remarks on the death of the Son of God know that we firmly believe in the divinity of Christ

"Many theologians really think that the Atonement, in respect to its dignity and efficacy, rests upon the doctrine of a trinity. But we fail to see any connection between the two.
 

To the contrary, the advocates of that doctrine really fall into the difficulty which they seem anxious to avoid.
 

Their difficulty consists in this: They take the denial of a trinity to be equivalent to a denial of the divinity of Christ. Were that the case, we should cling to the doctrine of a trinity as tenaciously as any can; but it is not the case. 

They who have read our remarks on the death of the Son of God know that we firmly believe in the divinity of Christ; but we cannot accept the idea of a trinity, as it is held by Trinitarians, without giving up our claim on the dignity of the sacrifice made for our redemption."

The Son of God by birth

“The Word was ‘in the beginning’. The mind of man  cannot grasp the ages that are spanned in this phrase. It is not given to men to know when or how the Son was begotten; but we know that He was the Divine Word, not simply before He came to this earth to die, but even before the world was created… We know that Christ ‘proceeded forth and came from God’ (John 8:42), but it was so far back in the ages of eternity as to be far beyond the grasp of the mind of man.”     

“It is true that there are many sons of God; but Christ is the ‘only-begotten Son of God’, and therefore the Son of God in a sense in which no other being ever was, or ever can be. The angels are sons of God, as was Adam by creation; Christians are the sons of God by adoption, but Christ is the Son of God by birth.”  Christ and His Righteousness p. 16 & 19
