The Doctrine of the Hypostatic Union

The doctrine of the hypostatic union is one of the most vital truths in Christology. Jesus Christ is one Person with two natures—undiminished deity and true humanity—inseparably united without mixture or loss of identity. Scripture testifies, “In the beginning was the Word, and the Word was with God, and the Word was God” (John 1:1), and further declares, “And the Word became flesh, and dwelt among us” (John 1:14a). Paul states, “For in Him all the fullness of Deity dwells in bodily form” (Col 2:9). These passages establish that the eternal Word, God the Son, took on true humanity in time, becoming the God-Man.

The Suffering of Jesus Christ

When God the Son added perfect humanity to Himself, this enabled Him to experience suffering and death with, and on behalf of, humanity. The suffering of Christ may be viewed in at least two ways: 1) His suffering during His time on earth prior to the cross, and 2) the suffering of the cross. As the God-Man, Jesus was perfectly holy in all His thoughts, words, and actions. Such perfect holiness brought with it a special form of suffering in this world that the rest of us could never know, since we are capable of yielding to the pressures of sinful temptation. When the time of His death was nearing, Jesus told His disciples “that He must go to Jerusalem, and suffer many things from the elders and chief priests and scribes, and be killed, and be raised up on the third day” (Matt 16:21; cf., Mark 8:31; Luke 9:22).

Jesus’ Ascension and Session

After Jesus’ resurrection, he appeared to many on several occasions. His final appearance was to His apostles. Luke wrote, “And He led them out as far as Bethany, and He lifted up His hands and blessed them. While He was blessing them, He parted from them and was carried up into heaven” (Luke 24:50-51). And in Acts we’re told, “He was lifted up while they were looking on, and a cloud received Him out of their sight” (Acts 1:9). It’s important to note that Jesus ascended bodily into heaven, and that He will return the same way. Jesus’ ascension into heaven was the beginning of His session at the right hand of God.
