Carl Jung: Self-knowledge, in the form of an examination of conscience, is demanded by Christian ethics.

God has indeed made an inconceivably sublime and mysteriously contradictory image of himself, without the help of man, and implanted it in man's unconscious as an archetype, the archetypal light not in order that theologians of all times and places should be at one another's throats, but in order that the unpresumptuous man might glimpse an image, in the stillness of his soul, that is akin to him and is wrought of his own psychic substance. ~Carl Jung, CW 11, Para 661

Self-knowledge, in the form of an examination of conscience, is demanded by Christian ethics.

They were very pious people who maintained that self-knowledge paves the way to knowledge of God. ~Carl Jung, CW 11, Para 661
