*Singing by a cappella means only (i.e., no musical instruments, though a pitch pipe may be used)
*Weekly observance of the Lord's Supper
**Technically Churches of Christ practice "[[closed communion]]"; however, in practice they do not prohibit visitors from taking communion, on the basis that according to I Corinthians 11:28 a visitor must "examine himself" and decide whether or not to participate (i.e. the minister, deacons, or elders do not decide who may or may not partake).
*Church governance by elders, supported by deacons
**The term "pastor" is rarely used among churches and the term "reverend" even less, due to lack of Biblical support for either name. Instead, terms used to describe the person giving the weekly sermon include "minister", "evangelist", or (if the person is also an elder) "preaching elder".
