Studies show that interfaith marriages are happening much more frequently than in the past. With increasing interfaith marriages often, unfortunately, comes interfaith divorce. Although many aspects of divorce are the same regardless of the religions of the spouses, one particularly unique issue in interfaith divorce becomes the religion of the children.
Even if one of the spouses converts to the religion of the other prior to or during the marriage, it is not uncommon for that converting spouse to return to their original religion upon a divorce. This situation raises serious complications for the children of the divorce, even if the parents had previously agreed to raise their children in one particular belief system. Think of the following real world example:
Bob, raised Jewish, meets Sue, who was raised Catholic. Before marrying, Sue converts to Judaism. The two have three children, whom they agree to bring up Jewish. When the parents divorce years later, Sue returns to the Catholic religion. Soon, an issue develops as to what services the children are/are not allowed to attend on the weekend with their respective parents.
