Brother Steaver, Which local assemblies are God's ordained institutions?
Act 2:41 Then they that gladly received his word were baptized: and the same day there
were added [unto them] about three thousand souls.
Act 2:42 And they continued stedfastly in the apostles' doctrine and fellowship, and in breaking of bread, and in prayers.
Act 2:43 And fear came upon every soul: and many wonders and signs were done by the apostles.
Act 2:44 And all that believed were together, and had all things common;
Act 2:45 And sold their possessions and goods, and parted them to all [men], as every man had need.
Act 2:46 And they, continuing daily with one accord in the temple, and breaking bread from house to house, did eat their meat with gladness and singleness of heart,
Act 2:47 Praising God, and having favour with all the people.
And the Lord added to the church daily such as should be saved.
This is the earliest account of believers gathering together for "bible study" (doctrine study) and fellowship. Why have you rejected this institute God has ordained by His word?
I find no exhortations in scripture to isolate oneself from other believers in the local community.
I have no problem with anyone forming an assembly of believers in their own home. But you are alone right now and need to get busy inviting other believers into your home. And as it grows you will need to appoint elders in accordance with God's instructions. And collect tithes and offerings for the furtherance of God's Kingdom work. You need to pray God for dirrection and purpose for your new assembly.
You did seek God on this issue, right? I pray you did not just follow your own heart and will. If it is of God then your assembly will grow and you will one day be given a title by the community. This will be your "denominational" label. Like it or not.
Welcome to God's way of gathering His flock and discipling them.
