What does God's absoluteness mean? According to a dictionary the word absolute means complete, free from imperfection, limits, restrictions, or mixture. Using this word in connection with God, we gain some idea of His infinity, supremacy, completeness, and purity. The Bible says (Deut. 4:35), "The Lord he is God; there is none else beside him." There is nothing, then, that can possibly limit or restrict God, mix or compete with Him.
A close study of the first three questions and answers in the chapter "Recapitulation" in the Christian Science textbook, "Science and Health with Key to the Scriptures" by Mary Baker Eddy (pp. 465 and 466), gives an enlarged sense of the absoluteness of God. All possibility of the actual existence of anything apart from God and His creation is ruled out.
In answer to the first question, "What is God?" Mrs. Eddy answers, "God is incorporeal, divine, supreme, infinite Mind, Spirit, Soul, Principle, Life, Truth, Love." Using spiritual sense, not the five physical senses, we perceive somewhat the absoluteness of Mind, gain a glimpse of the fact that there are not two realities of being, matter and Mind, but one only, Mind. What Paul calls the carnal mind, and what Mrs. Eddy calls mortal mind, which expresses itself as matter, is only a counterfeit of the divine Mind, God, and has no real existence.
