Justin PopovichWho is a Christian? A Christian is a man who lives by Christ and in Christ.

The commandment of the Holy Gospel of God is divine: “live worthily of God” (Col. 1:10).

God, Who became incarnate and Who as the Godman has in entirety remained in His Church, which lives eternally by Him.

And one lives “worthily of God” when one lives according to the Gospel of Christ.

Therefore, this Divine commandment of the Holy Gospel is also natural: “Live worthily of the Gospel of Christ” (Phil. 1:27).

Life according to the Gospel, holy life, Divine life, that is the natural and normal life for Christians.

For Christians, according to their vocation, are holy: That good tiding and commandment resounds throughout the whole Gospel of the New Testament.

To become completely holy, both in soul and in body, that is our vocation. This is not a miracle, but rather the norm, the rule of faith.

The commandment of the Holy Gospel is clear and most clear: as the Holy One who has called you is Holy, so be ye holy in all manner of life (1 Peter 1:15).

And that means that according to Christ the Holy One, Who, having been incarnate and become man, showed forth in Himself a completely holy life, and as such commands men: “be ye holy, for I am Holy” (1 Peter 1:16).

He has the right to command this, for having become man He gives men as Himself, the Holy One, all the Divine energies which are necessary for a holy and pious life in this world.

Having united themselves spiritually and by Grace to the Holy One—the Lord Christ—with the help of faith, Christians themselves receive from Him the holy energies that they may lead a holy life.

Living by Christ, the saints can do the works of Christ, for by Him they become not only powerful but all-powerful: “I can do all things in Christ Jesus who strengthens me” (Phil. 4:13).

And in them is clearly realized the truth of the All-True One, that those who believe in Him will do His works and will do greater things than these: “Verily, verily I say unto you: he that believeth in me, the works that I do he shall do also and greater works than these shall he do” (John 14:12).

And truly: the shadow of the Apostle Peter healed; by a word St. Mark the Ascetic moved and stopped a mountain…

When God became man, then Divine life became human life, Divine power became human power, Divine truth became human truth, and Divine righteousness became human righteousness: everything which is God’s became man’s.
