That’s great! Most house churches would be delighted to have you join them, as long as you are willing to be respectful of their existing culture and beliefs, while you are still working out your own beliefs. They would welcome you at whatever place you are in your spiritual journey. A few house churches may be uncomfortable with the idea of people who are not in agreement with certain Christian beliefs being in their meeting. They may think you will disrupt or try to change them. That’s why the most important thing is to be completely honest about where you are at, and to keep the discussion open. It’s interesting that in the gospel of John (1:46) Philip told Nathanael about Jesus. “Nathanael said to him, “Can anything good come out of Nazareth?” Philip said to him, “Come and see.” If you’re curious about what it means to be part of Christ’s community (flawed though we are), we invite you to “come and see”.
