The open door policy of many religious institutions has long been a way to add new members who are not born within the faith, and it is still practised today. Many churches have found that allowing non-members to attend their services provides them with the opportunity to help those looking for a new spiritual home. Each faith has its own requirements for those who wish to become members, but most of them are relatively easy for those joining.
Converting to a new faith is often done by those who feel they have not found what they are seeking in their current situation, and they are often looking for something different. Exploring other faiths is one way to seek spirituality, and many people will eventually settle into a new denomination. There is little said about it in modern times, but it was often a reason to be exiled from home or family in the past. Modern church goers have found acceptance in many different faiths, and they have found they can return to their original faith if they find no other communities that suit them.
Seeking a new faith is generally a spiritual journey for those who suddenly feel emptiness in their heart or mind, and there does not seem to be any one reason. Some people want more structure in their religious obligations, but others are looking for meaning in the scriptures of a religion. For those who prefer more pomp in their rituals, older churches are often more attractive. Established religions have also seen their members leave for churches with looser rules and less ritual.
Conversion to another faith remains an easy process, but staying with it can be difficult. Many people find the emptiness they experienced in their original faith was more about familiarity and restrictions, but they can come to crave them as they study their new faith.
