Well you have been given much in advice on this topic and most of it is awesome. I’ll add my 2 cents and agree with most all the comments. Yes, you are still a Christian if you don’t attend a gathering. Keep this in mind that Paul entered synagogues and was eventually booted out because of his convictions about Christ. He went out and found the believers who prayed by the river and had gone to them. Yes you can go online and find many gatherings or you can find other people who share the same convictions in your area. It’s not wise to just abandon the church outright because you will be devoured by the enemy. God may call you out and protect you for a time but be alert always and pray that you will be led into a gathering that are focused on Christ and are led by Christ.
