In Eastern Orthodoxy, God created humanity with the ability to freely love him and gave humans a direction to follow. Man (Adam) and Woman (Eve) chose rather to disobey God by eating from the Tree of Knowledge of Good and Evil, thus changing the "perfect" mode of existence of Man into a flawed or "fallen" one. Since then a fallen nature and all that has come from it is the result of this "Ancestral Sin". Because of the entrance of death into the world through Adam, all humans end up sinning and follow in his ways (Rom. 5:12, Heb. 2:14-15). Through the union of humanity with divinity in Jesus Christ the mode of existence of humanity is restored in the Person of Christ. Those who are incorporated in him may participate in this renewal of the perfect mode of existence, be saved from sin and death, and be united to God in deification (theosis). Ancestral sin is cleansed in humans through baptism or, in the case of the Theotokos, the moment Christ took form within her.
