The Bible does not mention any particular denominations as they had not yet formed during the period the Bible was written. What we are told is to meet with other believers regularly (Heb 10:24-25).
You should attend whichever church is teaching truly according to the Bible and where you will be helped to follow the way of Jesus Christ. It is important to check that what is taught is biblical and not just traditional church teaching.
Being part of a denomination makes it much easier to share fellowship with a wide circle of believers.
All the authors of this site are members of the Christadelphian group of churches because we believe that the Christadelphian understanding of the Bible is closest to what the apostles taught.
