There isn't a single, universally recognized name for a religion where someone believes in God but doesn't attend church. Here are a few terms and concepts that might apply, depending on the individual's specific beliefs and practices:
* "Non-denominational Christian": This person might hold Christian beliefs without being affiliated with a specific denomination. They might read the Bible, pray, and believe in Jesus, but prefer not to attend a traditional church.
* "Unaffiliated Theist": This is a broad term for someone who believes in God but isn't associated with a particular organized religion.
* "Spiritual but not religious": This phrase describes people who consider themselves spiritual and believe in a higher power but don't identify with organized religion.
* "Deist": Deists believe in God as a creator but don't think God intervenes in the world or that organized religion is necessary.
* "Christian Atheist": A paradoxial term, but often refers to someone who follows the teachings of Jesus, but does not believe in God.
* "Cultural Christian": A non-practicing person who identifies with Christian values and traditions.
The best term to use depends on the individual's specific beliefs and how they choose to identify themselves.
