I have heard many Christians profess the idea that as long as a person is praying to Jesus it doesn’t matter what church they go to. They say this out of charity, but it is not* completely* accurate. The Catholic belief is that elements of truth can be found in all the various religions, but only the Catholic Church has the full Truth, passed down from Christ to the Apostles and held intact, protected by the Holy Spirit today. For a
Catholic to know that Truth and turn against it would be heresy. My husband’s family is Lutheran. They tend to also be, to different degrees, against the Catholic Church. We have gone to my nieces’ and nephew’s Baptisms and have been to my husband’s grandfather’s funeral etc. We certainly don’t participate in Lutheran communion, although we were invited ,and encouraged, by the pastor and my husband’s sister to do so. We do not say thier creed. I say the Catholic Creed, but they are our family and we want to be there for these special moments. I am careful to explain ,with respect, the differences between the two religions to my children so that they know what is going on, etc. We still go to Mass if we attend a Lutheran service. A Lutheran service would not fulfill our obligation to weekly Mass, etc. My Mother in Law refused to go to my children’s Baptisms because they are in the Catholic Church, although my Father in law and sister in law, and her family, attended. The important thing to remember is to treat family members of various denomonations or faiths with respect, and love. Acknowlege the truths in thier faiths, but do not allow that to diminish or overshadow, the truth you know in the Catholic Church. Participation should not go against any Catholic teaching. Listening to the liturgy in the Lutheran Church is not a problem for me at all, the prayers are similar but when it comes to Communion and the Creed, etc. I dont’ participate because it woudl be heretical. I would not go if the denomonation was particularly anti-Catholic, because I would not be able to sit through something so heretical. A protestant wedding is usually short, and the Lutheran funeral service was much shorter than a Catholic funeral because they didn’t have communion. I certainly respect my husband’s family and do not want religion to divide us any more than it already has. My poor mother in law thinks her son joined some kind of cult that worships the Pope,( as well as many other misunderstandings) and no matter how much I have explained it, she holds her position. She even refused to call us Christian for several years.

It’s sad but I trust that God has a plan. I have been to Lutheran services about 5 times in my live, my daughter has been 2 times for her cousin’s baptisms and her great grandfather’s funeral, and my other two children have been once for their great -grandfather’s funeral. We only go for the “big stuff” Baptisms, weddings and funerals. Some might consider this wrong but I think it is important to share these moments with family, especially if there is a rift because of religious differences.
What do other members feel about going to historical sites from other religions? Would you go on a tour of the Pyrimids, Mexican ruins, etc? Would you tour a historical Protestant Church, Mosque or Synagogue, even if for architectural interest? Would you find this heretical? Just curious.
