Apophatic theology （negative theology）
https://en.wikipedia.org/wiki/Apophatic_theology
Apophatic theology, also known as negative theology,[1] is a form of theological thinking and religious practice which attempts to approach God, the Divine, by negation, to speak only in terms of what may not be said about the perfect goodness that is God.[web 1] It forms a pair together with cataphatic theology, which approaches God or the Divine by affirmations or positive statements about what God is.
