Christology is a branch of theology that concerns Jesus Christ, and it is translated from Greek as the study of Christ. It is the study of the nature (person) and work (role in salvation) of Jesus Christ, including his humanity and divinity, and the relation between these two aspects, and the role he plays in salvation. Christology is concerned with the identity of Jesus, and it asks how both his human and divine natures can exist in one person. The New Testament is taken to convey that the earliest followers of Jesus were convinced that God was revealed in him and that they attributed a number of titles to him, such as “Messiah,” “Son of Man,” “Son of God,” and “Lord”. Several approaches can be distinguished within Christology, including Christology from above or high Christology, which refers to approaches that include aspects of divinity, such as Lord and Son of God, and the idea of the pre-existence of Christ as the Logos (the Word), as expressed in the prologue to the Gospel of John. Christology is linked to several theological disciplines, including soteriology, ecclesiology, and Trinitarian theology. The basic sources for the historical development of Christology are the New Testament, containing the foundational Christian writings, the creeds of Christianity, especially those from the first five centuries, and the reflections of theologians. Christology is important because it helps us to understand the significance of the deity of Christ, demonstrates why Jesus is the atoning sacrifice for our sins, and is crucial to our salvation. An in-depth study of Christology has incredible personal impact on the believer’s daily life.
