I admire the courage it takes to bring this issue to us. It sounds like it has been bothering you for a long time and I appreciate the bravery to write about it here.
The therapist is helping make a link between the abuse, your sense of guilt, and feeling punished by god. Somehow the connection between these elements seems to be important.
The fact that it took you such a long time to acknowledge this with your therapist is also important and I would follow his insight as you keep exploring this. Since you’ve trusted the therapist for this amount of time, it seems very reasonable to continue the trust as it is part of the healing. Let him know the struggles you are having with being afraid.
