I belong to no Church, and never had. I studied with a few groups through the years, but never considered myself to belong to any single congregation, ever. My views vary between all the denominations and doctrines that you mentioned.Most people who say they are non-denominational belong to a congregation with the same doctrines. Like there are cessationist non-denominationalists, and continuist non-denominationalists. There are OSAS non-denominationalists, and Arminian non-denominationalists. What are your beliefs regarding these categories?
I am adamantly non denominational, no name comes before Jesus' name when I refer to myself. Only Christ saves, not Luther, Calvin, Rome, Presbyters, Bishops, Baptism, Pentecost, nor witness of the Holy Spirit outside of confessing Christ.
Faith in God's grace and Jesus' act of redemption, are the only names that I go by.
