Total depravity is a phrase or name that is used to summarize what the Bible teaches about the spiritual condition of fallen man. It is the “T” in the acronym TULIP, which is commonly used to enumerate what are known as the five points of Calvinism or the doctrines of grace. Because the name “total depravity” can cause people to have wrong ideas about what is meant, some people prefer to use terms like “total inability,” “righteous incapability,” “radical corruption” or even “moral inability.”
