Thank you for the question, brother Richardson. I am encouraged by your earnest desire to seek the kingdom and the righteousness of God.
In Hebrews 10:22-25, the Word instructs us to: “hold fast the profession of our faith without wavering; (for he is faithful that promised;) And let us consider one another to provoke unto love and to good works: Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another…”
It seems that it would be impossible to fully obey the injunction to be “not forsaking the assembling of ourselves together [with other believers]”, if we do not in fact commit ourselves to regularly assembling “together” with other believers.
In other words, if we were in fact to make it our purposeful habit to ‘assemble together, separately’, (to the neglect of any remaining possible option to assemble together), we would fail to capture the vision and guidance the Spirit has provided for us in the words of Hebrews chapter 10.
(And the goal of the Spirit’s instruction is always “charity out of a pure heart, and of a good conscience, and of faith unfeigned”, since “love is the fulfillment of the law”, and this law is “the law of the Spirit of life”.)
‘Assembling together, separately’ seems to be an oxymoron, and a logical contradiction.
However, I am entirely sympathetic to your most noble and pure intentions.
It could very well be that God has allowed you to experience such a circumstance so that by your pure, kind, and meek endeavors, and gentle example, you might be a positive influence in your area towards a more full and faithful adoption of the Kingdom life and principles by other professing Christians.
A positive witness of Kingdom Christianity is very needful in many of the the Churches of Christ mentioned by brother Doeringer. (I know many of the ‘churches of Christ’ and love them dearly, and could wish nothing more than that they catch a fuller glimpse of the historic faith, and aspire towards it, and rise up to meet it as an ideal that is most manifestly expressed in the Scriptures)
Whichever course of action you determine to take in your search of regular fellowship, I pray that God will bless you in it, and give you peace.
