Apollinarianism granted Christ a human body but not a complete human soul. But if Christ was to have a real incarnation it was necessary that He add to His divine nature not merely a human body but also a human mind or soul; for humanity consists not merely in the possession of a body but of a body and soul.

Christian Doctrine
What is the relationship between the gospel and the kingdom of God?
“The time is fulfilled, and the kingdom of God is at hand. Repent and believe the gospel.” The gospel is the good news proclaiming that the reign of God’s kingdom has come into this world.
How should we respond to the Holy Spirit in our worship and prayers?
Even though Christians insist that the Holy Spirit is fully divine, and that his works and personhood benefit us in many ways, we often don’t praise Him for these things in our worship, or even petition Him in our prayers.
Jesus was in the form of God
If Jesus is in the form of God, then He has all the essential attributes of deity, or all those characterising qualities that make God. Thereby, Jesus is in the form of God is God. Paul is merely stating that Jesus did not surrender His divine attributes but chose voluntarily not to use them or to set them aside. Hence surrendering the glory, majesty, and the prerogatives of deity, but not the deity itself.
Can we call Jesus God?
The Apostle John in affirming the deity of Jesus Christ in John 1:18, “No one has ever seen God; the only God, who is at the Father’s side, he has made him known”. Thus showing oneness of essence between Father and Son. In addition, Apostle John mentions in John 10:30, “I and the Father are one.” Thereby bearing upon the essential unity. It is interesting that whether the word “one” is neuter in gender, or literally, one thing.
Our Cross and His Yoke
To take up this end of our yoke with Christ, in the sense of entering into the ‘fellowship of his suffering, being made conformable unto his death’ is no different essentially from bearing each his own cross as we follow Christ. As an old gospel song says, ‘He always takes the heavy end and leaves the light to me’.
Modern-day Apostles?
There is much confusion in the contemporary sphere on the subject of apostles. This is mainly due to the climate of deep disagreement and resentment over some Christian leaders who are acknowledged by many to be modern-day apostles.
