The Greek particle eige (εἴγε) is an intensified conditional — a combination of ei ('if') and ge (an intensifying particle, 'indeed/at least'). It means 'if indeed,' 'since indeed,' or 'if at least' and carries an assumption of truth. It appears in 2 Corinthians 5:3; Galatians 3:4; Ephesians 3:2; 4:21; Colossians 1:23.
The particle eige is used in contexts that assume or appeal to a shared Christian reality. In Ephesians 3:2, Paul writes 'if indeed [eige] you have heard of the administration of God's grace that was given to me for you' — not genuinely doubting they know, but drawing them into acknowledgment. In Colossians 1:23, 'if indeed [eige] you continue in your faith, established and firm' — a pastoral appeal that assumes their continuance while urging its genuine enactment. This rhetorical use teaches that much of Christian exhortation operates this way: calling believers to be what they already are in Christ. The 'if' is not doubt — it is an invitation to align one's living with one's standing.
