I think Asia's past were clearly written in the first anime, she was abandoned by her parents in front of a small church, one day she realized that she has healing powers and became known as a "Holy Maiden". Then one day, she finds an injured person and heals him, the injured person turns out to be a Devil and she got scorned by the people from the church instead, she was even labelled as a "witch" and was kicked out by them.

And yes Xenovia is the first person to apologize to Asia for her insults to Asia, the other members of the church didn't even cared. They also showed the same treatment to Xenovia when she learnt that God died.
