ISB ~ 1 Corinthians 9 v22

all things to all men:Paul adapts himself to the needs and sensitivities of others. Without diluting the gospel message, he willingly sacrifices certain apostolic privileges that might hamper the effectiveness of his ministry to the world (9:20-21; CCC 24). His personal example should inspire the strong Corinthians to accommodate themselves to the weak (8:9-13).
