Many evangelical churches celebrate communion periodically – monthly or quarterly.
Yes
Weekly observance of the Lord’s Supper allows us to come together in unity through Christ and fellowship in an intimate manner through the worship of Jesus Christ. This purifies the body weekly.
No
There’s no clear command in Scripture as to how often we’re to receive the Lord’s Supper and for this reason, many churches have decided not to offer it weekly because they don’t want it to become routine or lose its special status.
