Wannano:
I realize full well that the CC does not rely on the Bible alone but I am wondering if you have Scripture that backs up the idea of everybody being born in separation from God rather than just with an inherited sin nature.
"For since death came through a man, the resurrection of the dead comes also through a man. 22For as in Adam all die, so in Christ all will be made alive. " I cor 15
“12Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all people, because all sinned—” Rom. 5
"1As for you, you were dead in your transgressions and sins, 2in which you used to live when you followed the ways of this world and of the ruler of the kingdom of the air, the spirit who is now at work in those who are disobedient. 3All of us also lived among them at one time, gratifying the cravings of our flesha and following its desires and thoughts. Like the rest, we were by nature deserving of wrath. " Eph. 2
We were, by nature, deserving of wrath, separated from God.
The Church teaches that we do have a fallen nature as the result of the sin of Adam, but also that the consequence is that we are separated from God because of this sin. Baptism washes away the of Adam as well as personal sins.
