On verses 44-45. While our Lord Jesus Christ was speaking among the Jews and working such signs, some, predestined to eternal life, whom He also called His sheep, believed. Others did not believe and could not believe, because by the hidden yet just judgment of God they were blinded and hardened.
They were abandoned by Him who resists the proud and gives grace to the humble (cf. Jas 4:6). Among those who believed, some confessed their faith so openly that, taking palm branches, they hastened with joy and exultation to meet Christ as He came.
Others, among the rulers, did not dare confess their faith, lest they be put out of the synagogue. The Evangelist reproves them, saying that they loved the glory of men more than the glory of God (Jn 12:43).
Among those who did not believe, there were some who believed later. These were the ones He foresaw when He said: “When you lift up the Son of Man, then you will know that I am He” (Jn 8:28).
Others would remain in this unbelief. They are represented by the Jewish people, who after these events were crushed in war, according to the prophecy written concerning Christ, and scattered almost throughout the whole earth.
When this happened to Him, and when His Passion was already drawing near, Jesus cried out and said: “He who believes in Me, believes not in Me but in Him who sent Me; and he who sees Me sees Him who sent Me” (Jn 12:44-45).
He had already said elsewhere: “My teaching is not Mine, but His who sent Me” (Jn 7:16). We then understood that He called the Word of the Father, which He Himself is, His teaching.
By saying, “My teaching is not Mine, but His who sent Me,” He indicated that He is not from Himself, but has His being from Him. For He is God from God, the Son of the Father. But the Father is not God from God, but God, the Father of the Son.
How, then, shall we understand what He now says, “He who believes in Me, believes not in Me but in Him who sent Me,” except in this way? He appeared to men as man, while as God He was hidden.
So that those who believed would not think that He was only what they saw, He desired them to believe in Him as the Father is. Therefore He said: “He who believes in Me, believes not in Me” (Jn 7:16), that is, not in what he sees Me to be, but “in Him who sent Me,” that is, in the Father.
But one who believes in the Father necessarily believes that He is Father, and therefore necessarily believes that He has a Son. For this reason, whoever believes in the Father must necessarily believe in the Son.
Yet let no one think of the Only-begotten Son what is thought of those who are called sons of God by grace and not by nature. The Evangelist says of them: “He gave them power to become children of God” (Jn 1:12).
To this belongs what the Lord Himself recalled as spoken in the Law: “I said, you are gods, and all of you sons of the Most High” (cf. Jn 10:34; Ps 82:6). Therefore He said: “He who believes in Me, believes not in Me,” to show that faith in Christ is not only faith in His humanity.
“So,” He says, “he believes in Me who does not believe in Me according to how he sees Me, but believes in Him who sent Me. Thus, when he believes in the Father, he believes that He has a Son equal to Himself, and then he truly believes in Me.”
For if he thinks that the Father has only sons by grace, who are certainly His creatures, and not the Word as Son, but only what was made through the Word, then he does not believe in the Father who sent Him.
If he thinks that the Father does not have a Son equal to Him and coeternal, eternally begotten, equally unchangeable, in no way different and in no respect inferior, then he does not believe in the Father who sent Him. For such a one is not the Father who sent Him.
Therefore, after He said, “He who believes in Me, believes not in Me but in Him who sent Me” (Jn 7:16). He at once added: “And he who sees Me sees Him who sent Me.” He did this so that people would not think He wanted the Father to be understood as Father of many children reborn through grace, and not as Father of the Only-begotten Son equal to Him.
Does He say here, “He who sees Me does not see Me, but Him who sent Me,” just as He said: “He who believes in Me, believes not in Me but in Him who sent Me”? He said one thing so that they would not believe in Him as He appeared, namely only as the Son of Man.
He said the other so that they would believe in Him as equal to the Father. “He who believes in Me,” He says, “does not believe in what he sees in Me, but believes in Him who sent Me.
Or, if he believes in the Father who begot Me equal to Himself, let him believe in Me not as he sees Me, but as in Him who sent Me. For there is so little difference between Him and Me that he who sees Me should see Him who sent Me.”
The Lord Christ certainly sent His apostles, as follows from their name. For as the Greek word “angels” means “messengers” in Latin, so the Greek word “apostles” means “those sent” in Latin.
Yet would any apostle have dared to say, “He who believes in me, believes not in me but in Him who sent me”? None of them would have said at all, “He who believes in me.” We believe the apostle, but we do not believe in the apostle, for the apostle does not justify the ungodly.
But to the one who believes in Him who justifies the ungodly, his faith is reckoned as righteousness (Rom 4:5). An apostle could say, “He who receives me receives Him who sent me.” Or, “He who hears me hears at the same time Him who sent me.”
For the Lord said this to them: “He who receives you receives Me; and he who receives Me receives Him who sent Me” (Mt 10:40). We honor the master in the servant, and the father in the son. But the father is, as it were, in the son, and the master, as it were, in the servant.
The Only-begotten Son, however, could with full right say: “Believe in God, believe also in Me” (Jn 14:1). He could also say what He now said: “He who believes in Me, believes not in Me but in Him who sent Me” (Jn 7:16).
He did not turn away from Himself the one who believed in Him. Rather, He did not wish the believer to perceive Him only in the form of a servant. For whenever anyone believes in the Father who sent Him, he simultaneously believes in the Son, without whom the Father cannot be conceived.
And he believes in such a way as to regard Him as equal, for it is said: “He who sees Me sees Him who sent Me” (Jn 12:45).
