Thank you for your interesting post.
My view of "sacraments" is perhaps somewhat complex, as are many of my views. Some people on this forum have labeled me a heretic because they can't pigeonhole me. It would be good to have a discussion without being labeled.
I wouldn't use the word "symbol" to refer to the sacraments. I would call them signs. Some would say there is no difference, but to me there is -- even if a subtle one. I do believe God can and does work through the physical, not just that He uses the physical to work within us, although He does this, too. Because I believe this, I would not limit the sacraments to just two, or seven; rather, I think sacraments are innumerable.
While I believe God works through the physical, I don't believe He works at the behest of man -- I don't think God automatically does something because a human being pronounces certain words or formulas over another person. I have a favorite saying: "The Spirit bloweth where it listeth, not where man listeth that it should blow." That is just one reason that I do not believe in baptismal regeneration.
I've never known exactly where my views fit in. I couldn't be Roman Catholic, or any type of Reformed Christian. I like Eastern Christianity for the reasons I stated, but I have important differences that preclude me from being in the EOC.
I don't believe in infant baptism, but I believe water baptism and the other "sacraments" are more than merely symbols -- but not the way the Churches of Christ do, for instance. I believe in all the gifts of the Spirit being in operation today -- but not as the Pentecostals believe and define it. I used to think I was a Quaker, but I wouldn't do away with the outward, physical sacraments, and I am not a complete pacifist. Also, their views on perfection are close to Wesleyanism, while mine are not.
I would probably fit best with the General Baptists.
But to get back to the specific point of your post: I have some affinity, I believe, with your view of sacraments, but I would probably fall somewhere between your views and those who regard them as only symbols.
Again, thanks for your post; I like to discuss things like this, and in this manner. I lose my temper sometimes and can be rather sarcastic in my replies, but I don't start out that way -- at least I try not to.
