Considering yourself to be among those who believe in the principles of this path merely means you truthfully and wholeheartedly agree to follow the Three Tests
of PEACEFULNESS, TRUTHFULNESS and CHOICE in your life, while allowing the same latitude of belief for others.
Think of it this way: if you are a Christian, you consider yourself to be Roman Catholic, or Greek Orthodox, perhaps Lutheran or Pentecostal or Southern Baptist, or Church of Christ, and so on. You may be a Mormon. If you follow Judaism, you may be Orthodox, Conservative or Reform. If you follow Islam, you may be Sunni or Shia or perhaps are most comfortable identifying as Sufi. These are all variations of the great underlying spiritual ideals that inspired them.
Establishment of Religion should be considered in the same way. You do not renounce any of your previously held beliefs, unless of course you wish to. We have no need of a membership roll or donor list. Your sincere attempt to live the principles espoused here is all the commitment sought, and all that will ever be asked of you.
