When he was around five and ready to start religious education, Patti said they made the decision to raise Seth, who is now 16, Jewish.
"I went through a lot of guilt," she said. "I have parents and family who are still very much Southern Baptist and believe there is only one way to get to heaven."
"If you are good people and lead a good life," Mark said, "God will take care of those decisions."
Patty, who said interfaith marriages are not for the "faint of heart," realized it was time to choose between her family and and the family she and her husband had created.
"Whatever the issue, in any relationship, one of the parties has to show greater flexibility and willingness to accomodate the other," Mark said, pointing out that Patty was able to do that in their marriage.
But, he added, it's also important that interfaith couples be flexible, respectful and open-minded about each other's religions. Patty has served in prominent positions on Jewish community boards and she and Mark belong to an interfaith group, where he has studied the New Testament for the first time.
Ultimately, Mark said his life is richer for marrying Patty. "I would not have learned as much as I have without my interfaith marital experience," he said. "It's been challenging at times, but all in all I've had a great life."
