God is not a God of chaos he is a God of order. If creation teaches us anything God orders the choas, he spearates it and he speaks light into it.
The world is full of competing doctrines and millions who follow them claiming the exact same things you are that the learnt and unlearnt alike come to their system's conclusions. This is just Christian tribalism, we all want to be on the winning side so applaud only the accounts that cheer our own position. Talk to any Christian from any background and they can tell you similar accounts. This is a testament not to our denominations but that God speaks through and uses our limited systems even when they are in competition with each other. I'm not at war with you nor am I challenging you to leave the SDA church, you are my brother and I am simply challenging the way you approach scripture so that you may serve God better where God has called you.
I was raised in a denomination that I am still very strongly a part of. There's stuff I dont like, but there is a lot stuff I do like and I don't feel God is calling me away from this community. I also meet with other Christians of different backgrounds and we share, pray and encourage each other. My denomination is like the passport I hold of where I come from, but I don't fly my denominational flag I fly the flag of Christ. Currently I am not in an area with a church so I don't attend any formal setting but I'm still accountable to a Christian community who know me and my family well. I don't consider myself x denomination by identity (or interdenomination/nondenominal, etc...), I'm a follow of Christ first, and my denomination is held loosely, not because I have no commitment, i'm active in the fellowship and have no intentions of changing. I hold it loosely because Christ tells me if I want to follow him I must deny myself first, so my desire for tribalism or comparison to others needs to be denied.
You may feel called in SDA ciricles, as I'm feel called where I am, but we can test these doctrines to see how biblical sound they are. A doctrine that relies on dividing laws to descriminate against law is not a biblical revealed methodology and there's no other way to put that. You may argue I am relying on logical devices too much (I'm a computer programmer too) not faith but what are you calling me to have faith in? Faith in an unsupport biblical doctrine? So if it's not from the bible than what or who am I basing my faith in? And there's the problem.
I keep sola scriptural, so all droctrines are validated by scripture alone. I cannot find anywhere in Scripture where it instructs me to divide law, then only follow the hand picked ones. Call that logical or not, but to me it is about being honest in how I approach scripture. I'm fine with unanswered aspects but not when doctrines hinge on things the bible never speaks of.
I would encourage you to stay in the SDA church if that is where God is calling you. I feel the call to peace is greater than these imbalances withun these systems (as they are too great and wide spread) and we can be an active member serving within. But I am challenging you how you approach scripture, your justifications for these things are just too absent in scripture that I can't agree with you on those points and why would you expect any less of me? as these are serious matters that deserves attention and focus so that we understand how we should apply them.
