I have read with great interest and I trust with due care the Rev. C. Van Der Donckt's Reply to my discourse on "Mormon Doctrine of Deity." With regard to his Reply in general, I observe three things: first, the Reverend gentleman labors with some pains to demonstrate that "Mormon" views of Deity with respect to the form and nature of God are at variance with the Catholic and even the orthodox Protestant views on that subject; second, the "Mormon" views of Deity are in conflict with the accepted Christian philosophy; third, that "Mormon" doctrines stand in sharp contrast to both Catholic and Protestant ideas respecting the unity of God. All this is easily proved; and would have been conceded cheerfully without proofs. "Mormons" not only admit the variances but glory in them. The foregoing, however, is not the issue between Mr. Van Der Donckt and myself. After the variances referred to are admitted, these questions remain: Which is most in agreement with what God has revealed concerning his form and nature, "Mormon" or orthodox Christian doctrine? Which is most in harmony with sound reason and the scriptures, "Mormon" doctrine, or the commonly accepted Christian philosophy? Which in their teaching presents the true doctrine of God's unity, "Mormons" or orthodox Christians? These are the issues; and so far as the Reverend gentleman has maintained the orthodox Christian doctrine against the "Mormon" doctrine, I undertake to controvert his arguments. I. THE FORM OF GOD. Following the order of my treatise, the gentleman first deals with the form of God. His first premise is that "_God is a Spirit_," quoting the words of the Savior (John 4:24;) and Paul's words, "The Lord is a spirit," (II Cor. 3:17.) He then argues that a spirit is different from a man, and quotes the remark of Jesus to his disciples, when he appeared to them after his resurrection: "A spirit hath not flesh and bones as ye see me have" (Luke 24:37-39). Also the words of Jesus to Peter, "Flesh and blood hath not revealed it [that is, that Jesus is the Christ] unto thee, but my _Father_ who is in heaven." (Matt. 16:17.) The gentleman in all this sees a striking contrast between _men, flesh and blood,_ and the _Father_; which "conveys the sense that God hath not flesh and blood like man, but is a spirit." That God is a spirit Mr. V. holds is proved also from his being called "invisible" in the Bible; and from this premise argues: "All material beings are visible. Absolutely invisible beings are immaterial, or bodiless:" and therefore, to help the gentleman out a little, not like man in form.
