Rape is a hard problem to "solve". Modern society has allowed equal protection for all peoples, regardless of gender, race, religion, et cetera. Sometimes it doesn't seem like that,but society is getting better. Discrimination(not the immorality kind) is necessary when dealing with any problem, not just rape. Men and women are biologically different so traumatic events are dealt with differently. In the same way, any treatment must be specialized. If they are religious, their god(s) are a great comfort to them and can help them cope with such trauma.
So how should a Christian deal with rape? Ideally, love should be shown. Love conquers all and heals all. Love is the light that thins out the darkness. Love is what makes the world go round. Forgiveness is a big part of that, but that doesn't mean the victim needs to heal. We are humans led by a supernatural force, we need time to cope. Patience is a virtue, and let us not forget that we mourn with those who mourn.
Ultimately, the psychology side should be left with the professionals. But we are triune beings, we have a mind, body, and spirit. Let the psychiatrists deal with the mind, the doctors to deal with the body, and the theologians to deal with the spirit.
