"All the believers devoted themselves to the apostles’ teaching, and to fellowship, and to sharing in meals (including the Lord’s Supper), and to prayer." Acts 2:42
This is the simple way of "being church" that allows for unity and cooperation with others who likewise love God, but belong to other denominations. Our different applications of biblical principles can become our strength if we are willing to build these bridges with others who are faithful followers of Jesus. Our gatherings are never on Sunday mornings so that people are encouraged to remain in their own denominations or non-denominational groups.
