A.W. Pink writes:
“The Lord Jesus Christ could not sin because He was the ‘Holy One of God.’ Before He was born into the world it was said to Mary, ‘The Holy Spirit shall come upon thee, and the power of the Highest shall overshadow thee: therefore also that Holy Thing which shall be born of thee shall be called the Son of God’ (Luke 1:35). Speaking reverently then we say, that the will of the Son of Man was not in a condition of moral equipoise, that is, capable of turning toward either good or evil. The will of the Lord Jesus was biased toward that which is good because, side by side with His sinless, holy, perfect humanity, was His eternal Deity” (A.W. Pink, The Sovereignty of God; italic emphasis Pink’s).
God-hater Charles Hodge affirmed that Jesus Christ COULD sin — that is, Charles Hodge DENIED the absolute purity and holiness of Jesus Christ. Charles’ demonic descant was upon the theme of “sinlessness”:
“The Mediator between God and man must be sinless. Under the law the victim offered on the altar must be without blemish. Christ, who was to offer Himself unto God as a sacrifice for the sins of the world, must be Himself free from sin. The High Priest, therefore, who becomes us, He whom our necessities demand, must be holy, harmless, undefiled, and separate from sinners. (Hebrews vii. 26.) He was, therefore, ‘without sin.’ (Hebrews iv. 15; 1 Peter ii. 22.) A sinful Saviour from sin is an impossibility. He could not have access to God. He could not be a sacrifice for sins; and He could not be the source of holiness and eternal life to his people. This sinlessness of our Lord, however, does not amount to absolute impeccability. It was not a non potest peccare. If He was a true man He must have been capable of sinning. That He did not sin under the greatest provocation; that when He was reviled He blessed; when He suffered He threatened not; that He was dumb, as a sheep before its shearers, is held up to us as an example. Temptation implies the possibility of sin. If from the constitution of his person it was impossible for Christ to sin, then his temptation was unreal and without effect, and He cannot sympathize with his people” (Charles Hodge, Systematic theology, Volume 2, p. 457; emphasis mine–CD).
