Angelism
Angelism is a theological concept referring to ideas and philosophies which regard the human being as essentially angelic, and therefore sin-less in actual nature. The term is used as a criticism, to identify ideas which reject conceptions of human nature as being (to some degree) sinful and lustful:
"[Angelism] minimizes concupiscence and therefore ignores the need for moral vigilance and prayer to cope with the consequences of original sin."
