The Double in literary criticism and The Trinity in Christian theology: Multiple personality is suspected in the former, but never in the latter 

“According to the church father Augustine anyone who denies the Trinity is in danger of losing her salvation, but anyone who tries to understand the Trinity is in danger of losing her mind” (1, p. 1).

And since “There is no mention of the word ‘Trinity’ in the New Testament” (1, p. 6), how did The Trinity become central to Christian theology?

Is it an interpretation of what the New Testament does mention: the Father, the Son, and the Holy Spirit? But if the New Testament had intended God to be thought of as The Trinity, would it not have said so, explicitly?

As I read The Gospel According to Mark, Jesus proves his divinity by performing miracles, especially by healing through exorcism, the essence of which is to cast out “unclean spirits” or “demons.” And Jesus is able to do that after he is baptized and possessed by the Holy Spirit.

Thus, the gospel does not introduce the Holy Spirit for the purpose of providing a concept of God, but as a way to explain why Jesus is able to exorcise unclean spirits.

Literary criticism of “the double” sometimes mentions multiple personality. But theological literature on The Trinity does not mention it (1, 2).
