Original Sin

Concise Bible Dictionary:

This term is often used by theologians, but they are not agreed as to its signification. It is not found in scripture. Man has derived an evil nature from Adam, but his sins are his own. Death passed upon all men because of Adam’s sin, but all have sinned (Rom. 5:1212Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned: (Romans 5:12)).
