Some Christians interpret the word "heart" in Bible as a synonym of Freud's "unconscious".
Psychoanalysis can be understood by Christians as a scientific theory of sin.
This way Christianity and psychoanalysis can be reconciled, as far as practicing psychoanalysts do not persuade a patient to a sin.
Christians should admit that they are also sinners. This way we need help of a good psychoanalyst.
Some may say "God is my psychoanalyst.", but we may assume that God can use other people to help us cleanse from a sin.
