The Greek adjective aischros (αἰσχρός) means shameful, base, dishonest, or dishonorable. It describes conduct or character that violates the standards of honor and decency, rooted in the Greek concept of aischyne (shame).
Paul uses aischros in the context of Christian ethics. In 1 Corinthians 11:6, unveiled women in worship are called shameful — reflecting cultural honor codes. More theologically, Ephesians 5:12 declares: 'It is shameful (aischron) even to mention what the disobedient do in secret' — contrasting the fruitful light of transformed lives against the darkness of shameful deeds. Titus 1:11 warns against false teachers motivated by 'shameful (aischrou) gain.' The Gospel transforms the very categories of honor and shame, pointing to the cross where Christ bore our shame to restore our honor before God.
