I didn't realize some brands of Christianity don't have doctrines or creeds that they follow. I imagine fairly liberal ones like the United Church or something where you can believe whatever? Most churches I visited had a 'what we believe' on their website that read like religious beliefs....ie We believe that Jesus is the Son of God, was crucified, etc, etc. What churches allow belief that Jesus was the Son of God optional? Pretty progressive if you ask me.
I don't consider myself religious but I don't deny some aspects of my Buddhism are actually religious. Any organized set of beliefs are in fact a religion, whether one likes to call themselves that or not. I think what Jane meant by religious or religion is how it boxes one in and sets them on a path that is very straight, without much leeway to go in different directions. In my mind a key component of being 'religious' is having to believe a particular thing and not being able to 'experiment' different ideas.
There are no "brands" of Christianity. There is only salvation by Grace through Faith. An authentic Christian cannot be identified as Roman Catholic or Southern Baptist or Lutheran or Methodist or whatever. One who has confessed Jesus as Savior is a Believer, not a denomination. There are no variations in the Good News that eternal security is freely offered by God. No structure (religion), no rules, no policies, no procedures.
At the moment of receiving God's free Gift of Grace, one is placed on a Pathway to eternity. No power on earth, no cult, no belief minus Grace, can, and never will, change that. It is unalterable. Nothing on the Pathway is predestined. God does not plant difficulties or pain or suffering along the Way. The only Presence is Grace. God's Amazing Grace is present from the initial Gift, for eternity. One does not "work" or "seek" to remain saved thereafter. Grace is free. His Embrace is eternal. There is no "striving" to please Him. He was pleased at the precise split-second of our confession. That never changes.
The naysayers, counterfeit Christians, straying Christians, will jump on the bandwagon of "so I can sin all I want and I'm forever saved." They ignore the the Truth that Jesus paid the price of every sin one could ever commit at the Cross. They don't understand that. They would rather doubt, argue, debate, rather than accept that Glorious Truth.
That does not entitle an authentic Christian to sin. Scripture makes that clear. An authentic Christian sins, yes, but he or she is no longer a sinner by standing or status before God. He or she is forever forgiven. An authentic Christian grieves over incremental sins, knowing full-well that those acts disrupt the Path God has placed him or her on. In simple, simplistic terminology, one "falls off the wagon." He or she in no wise becomes "lost" again (one who does not know Jesus is Biblically identified as "lost.") Those incremental sins can have destructive impact on self, family, friends, co-workers, strangers. They have a definite impact at the Judgment Seat of Christ, where each authentic Christian's witnessing to others about our Savior is measured. As authentic Christians we are called upon to share with others God's Amazing Grace, Romans 10:8-13.
How does one say "God, I'm sorry.... I've sinned." Open your Bible to 1 John 1:9. Read that 3 or 4 times. God is faithful and just in forgiveness. When He hears each acknowledgement He "looks at me, He sees not what I used to be --- He sees Jesus." I've been redeemed.
