In the Orthodox tradition, Jesus Christ is called the Messiah, the Savior, and also the God-man.
The latter term appears in Christianity in the first centuries during the controversy over the deity and humanity of Jesus Christ.
The naming of the Savior by the God-man indicatesThe duality of natures (natures) in Jesus Christ. So, according to the teaching of the Orthodox Church, the Lord Jesus Christ is the true God - God in essence in the literal sense of the word, and also a perfect man. Orthodox dogmatic doctrine announces to people that in a single second person the Holy Trinity (Jesus Christ) after the moment of the incarnation became two natures: the divine and the human. These two natures in Christ do not merge into one, they do not separate, they do not go over into one another, but from the moment of the incarnation they are inseparable in the one second person of the Holy Trinity.
Speaking of Christ as a God-man, it is necessaryTo understand that Jesus possesses all the fullness of the divine authority, equal to God the Father and the Holy Spirit. Christ has all the divine properties. The only difference between Christ in the deity of God the Father and the God of the Holy Spirit is the "birth" from God the Father. Orthodox theology gives a distinction between divine persons in terms of fertility and origin. So, God the Father is not born or born from anyone, God the Son is born of God the Father, and God the Holy Spirit proceeds from God the Father.
It is necessary to say about the humanity of Christ. The Savior was like people in everything except sin. Christ was a perfect man, a man without sin. The Savior, like people, had human emotions, sadness, joy, a sense of thirst and hunger. So, in the Holy Scripture it is said that Christ wept over the dead Lazarus, mourned, thirsted on the cross. These manifestations of humanity in Christ are called natural passions, which have nothing to do with sin.
