Why did Christ accept circumcision, and what is the spiritual meaning of this event? Of course, one can say that He was little then. But He allowed this to happen, and therefore, despite the fact that He was little, this event has spiritual content. So what is it? To confirm that "salvation is from the Jews" (John 4:22)? Or to pass through the whole path of His humility, limiting Himself not only by human appearance but also by all the limitation of human culture?
It is also certain that He knew that after Him the apostle Paul would come, sternly rebuking all who do not understand the full limitation of this rite, as of every rite in general. In the Epistle to the Romans alone he speaks of this more than once; see chapters 2, 3, and 4. For example: "For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh" (Rom. 2:28), or "Circumcision is nothing and uncircumcision is nothing, but keeping the commandments of God" (1 Cor. 7:19).
The Lord knew this and still allowed His circumcision to take place. In this is His humility before the Law, which He came to fulfill (Matt. 5:17), and this is precisely what allows the apostle Paul to say: "In Him you were also circumcised with a circumcision made without hands, in the putting off of the body of the flesh, by the circumcision of Christ" (Col. 2:11).
