I disagree with our eschatology and view of death (i.e. Soul Sleep) however I agree with the overwhelming majority of our other doctrines and will actively argue for them. I've found it hard to read Galatians, Romans & Hebrews while holding to a doctrine that boils down to "
those who keep this specific commandment of The Law will be saved". I believe it is good to keep the Sabbath, even moral to do so in the same way to get married is (Genesis 2:3 is the strongest argument for keeping the Sabbath), however it does not define salvation the same way "
thou shalt not steal" does not define it. Jesus Christ being the
author and finisher of our salvation means that anything that came before does not grant it. We're bound to Him by faith, not by any work of The Law.
To keep the Sabbath in faith however is extremely beautiful and was God's desire for man to rest in Him, the same way it was His desire for us not to eat meat (even though there's nothing wrong with eating meat). So to your point, regarding the Sabbath I'm essentially SDA in practise or can be, but the doctrine & arguments used to get there are completely different as I believe the traditional use of The Law fails to justify the doctrines Adventism intends to teach. I understand that may not be
traditional but I find I have no other Church home to go to with what I believe Scripture teaches and that Adventism is the only place I can be. The Liberal forms of Adventism are as a rule
far too liberal but the traditional streams of Adventism are far too the other way; there seems to exist no place in the middle :\.
God bless
