Incurvatus in se
Incurvatus in se is Latin for "curved inward on oneself." The concept was developed by Saint Augustine of Hippo and expanded by Martin Luther. It refers to the mindset of focusing on oneself rather than focusing outwardly on God and the church community. People who are incurvatus in se consequently have no hesitation to sin.
