Discipleship Points: Various parts of these verses may cause concern to a believer, like unworthy manner, examine oneself, drinks judgement. The best understanding is these refer to an unsaved person taking communion. Believers are not made right with God by their performance. If we have a sin, we confess, He forgives and cleanses us from ALL unrighteousness (I John 1:9.) Our New Covenant/New Testament relationship shows the verses as well as others refer to unbelievers who are not possessors of salvation but only professors.
