I am also no theologian but my understanding is that the consequence of the sin of Adam is the destruction & degradation of man's original nature (an icon of divinity destined for theosis) into a fallen state, disposed to sin, corrupt in spirit and body, darkened in the nous. And Christ's assumption of human nature and conquering of death healed mankind's fallen state from sin and death and provided the healing path toward reunification with God and restoration to our intended state, to all who accept Christ. But the Orthodox perspective as far as I have learned is that we are not to judge Adam as any of us in our fallen state as sinners would surely have fallen too. So in that sense we are not 'innocent' of Adam's guilt of sin, but nor is God judging you or me for eating the fruit... we have our own sins to answer for.
