“But of that day or hour NO ONE KNOWS, not even the angels in heaven, nor the Son, but the Father alone”
Unitarians, esp. Muslims and JWs use this passage (among others) to show Jesus is not God.
First, throughout the OT and NT, Christ is presented as ontologically truly God and truly man (Exod. 3:6, 14; Isa. 9:6; Dan. 7:13-14; John 1:1, 18; 5:17-18; 8:58; 20:28; Rom. 9:5; 10:9-13; Phil. 2:6-11; Titus 2:13; Heb. 1:6, 10-12; 2 Pet 1:1; Rev. 1:7-8; 22:13). His claim to be God were unambiguous (Mark. 14:61-64; John 5:17-18; 8:24, 58 et al.; 10:30; Rev. 1:7-8; 22:13; etc.).
So was Jesus ignorant of His Return?
The simple response has to do with the verb oiden (“knows”). Instead of ignorance (Jesus not “knowing”), we see the verb oiden (perfect form of eidō) in a “preeminent sense” in that, the verb oiden takes the force of the Hebrew stem hiphil. Verbs with the hiphil has a causative or declarative sense. Thus as here: “I make known, cause, promulgate, declare.”
In 1 Cor. 2:2, the same verb is used in this sense, where Paul states: “I determined ‘to know’ (eidenai from eidō) nothing among you but Jesus Christ and him crucified,” that is, I cause or determined to make known, nothing among you, but Jesus Christ.
So in light of the verb oiden (“to know”) taking the force of the Hebrew stem hiphil (as in 1 Cor. 2:2), the literal sense would be: “But of that day and that hour none can cause or declare to you to KNOW (that is, none has authority) to cause to make known— not the angels, neither the Son, but, preeminently, the Father alone—He will reveal or declare it.
Therefore, in Mark 13:32, the verb takes the force of the Hebrew hiphil stem (causative or declarative sense)—i.e., in a “preeminent sense” (as in 1 Cor. 2:2). Thus, the Son “knows” the day and hour of His return, but the one who will make known, cause, promulgate, or declare is the Father alone. A proper exegesis erases any notion of the Son being ignorant of His return.
“To them belong the patriarchs, and from them, by human descent, came the Christ, who is God over all, blessed forever! Amen” (Rom. 9:5, NET).
