We are also an interfaith family. My husband, Gene is of the reform Judiasm faith and I am Roman Catholic (and from a large Irish Cathoilc family). My step-daughters were raised Jewish and our 2 sons, Josh and Michael are being raised Catholic. This is a great topic. As a family, we try to honor the traditions of both faiths -- and blend our spiritual values --- and model those values for our children. It is not always easy.
Early on in our marriage, I attended an Introduction to Judiasm class at Gene's temple. I learned about both the history and the cultural traditions of the Jewish faith, which in turn helped me to understand and participate in the Jewish holidays and to be an active member in helping Gene carry-on the Jewish traditions with our family. My in-laws also taught me some Yiddish, which I enjoy using from time to time.
A big challenge for us was in finding a catholic church that was more "liberal" in their doctrine and therefore, more accepting of us as a spiritual interfaith family and a multi-cultural family. After some "church shopping", we settled on a church in our town that is very multi-cultural in both the parishoners and in the staff of the church. There are Sunday Masses in both english and spanish and the church offers an array of social and recreational services to the community. It is not a perfect match to family spirtual values, but it is closer than other churches in the area. Josh (age 7) is attending religious education classes at our church, after school one afternoon a week. It is a struggle each week to get him to attend the classes and he resists going to church each Sunday. He is beginning to notice the differences in values between home and the church and he is wondering whether he should be raised Jewish instead of Catholic. I wonder if it is because we are not a strictly Catholic home, as we also honor some Jewish traditions like the Jewish holidays, Friday shabbot dinners, engaging in mitzvahs, etc. And, our family values might be considered more liberal than other Catholic families.
So, is our family a successful interfaith family? No, I think we will always be a work in progress. However, that is ok -- it means we continue to explore who we are and what we may become.
