Divinity of Jesus in the context of "Kyrios"

In Christianity, God is the eternal, supreme being who created and preserves all things. Christians believe in a monotheistic conception of God, which is both transcendent (wholly independent of, and removed from, the material universe) and immanent (involved in the material universe). Christians believe in a singular God that exists in a Trinity, which consists of three Persons: God the Father, God the Son, and God the Holy Spirit. Christian teachings on the transcendence, immanence, and involvement of God in the world and his love for humanity exclude the belief that God is of the same substance as the created universe (rejection of pantheism) but accept that God the Son assumed hypostatically united human nature, thus becoming man in a unique event known as "the Incarnation".

Early Christian views of God were expressed in the Pauline epistles and the early Christian creeds, which proclaimed one God and the divinity of Jesus. Although some early sects of Christianity, such as the Jewish-Christian Ebionites, protested against the deification of Jesus, the concept of Jesus being one with God was accepted by the majority of Gentile Christians. This formed one aspect of the split of early Christianity and Judaism, as Gentile Christian views of God began to diverge from the traditional Jewish teachings of the time.

Mere Christianity is a Christian apologetical book by the British author C. S. Lewis. It was adapted from a series of BBC radio talks made between 1941 and 1944, originally published as three separate volumes: Broadcast Talks (1942), Christian Behaviour (1943), and Beyond Personality (1944). The book consists of four parts: the first presents Lewis's arguments for the existence of God; the second contains his defence of Christian theology, including his notable "Liar, lunatic, or Lord" trilemma; the third has him exploring Christian ethics, among which are cardinal and theological virtues; in the final, he writes on the Christian conception of God.

Mere Christianity was published in the United Kingdom by Geoffrey Bles on 7 July 1952. While initial reviews to the book were generally positive, modern reviewers were more critical of it, and its overall reception was relatively mixed. The praise was primarily directed to Lewis's humorous, straightforward style of writing; the criticism was primarily around the validity of his trilemma, which defends the Christian doctrine of the divinity of Jesus, and how he should have considered providing more choices.
