Should you pass judgment on sinners or non-Christians? (Q78)
From To Be A Christian, An Anglican Catechism
No. God alone judges those outside the Church. The Church may proclaim God's condemnation of sin and may exercise godly discipline over members who are unrepentant; but I am called only to judge between right and wrong, to judge myself in the light of God's holiness, and to repent of my sins. (Matthew 7:1-5, 1 Corinthians 5:12-13; 1 Corinthians 11:31)
