A common misinterpretation is to view self-examination as requiring sinless perfection or exhaustive confession of every possible fault before Communion, which burdens believers unnecessarily and contradicts the gospel of grace; instead, it calls for honest reflection on one's relationship with Christ and the communal body, not legalistic perfectionism. Another error is applying it individualistically without regard for the corporate context of unity in the church, or using it to judge others' worthiness rather than self-assess, which Paul warns against as the role of God alone.
I Corinthians 11:28
King James Version (1769)
28 But let a man examine himself, and so let him eat of that bread, and drink of that cup.
In the context of addressing abuses during the Lord's Supper in Corinth, where some partook selfishly and disrespectfully leading to judgment like illness or death, this passage instructs believers to personally examine their hearts and attitudes beforehand, ensuring they approach the bread and cup with reverence, repentance for any known sin, and a discerning recognition of Christ's body and blood symbolized therein, thus partaking worthily to proclaim His death until He comes.
