1 Corinthians 9:5

Have we no right to lead about [in our constant journeyings] a wife that is a believer [i. e., a lawful wife; it was unlawful to marry an unbeliever-- 2 Corinthians 6:14-16], even as the rest of the apostles [this passage creates a fair presumption that at least the majority of the apostles were married], and the brethren of the Lord [For their names see Matthew 13:55. For their relation to Jesus, see "Fourfold Gospel," pp. 119, 224-226], and Cephas? [This apostle was married (Matthew 8:14); yet Catholics claim him as the first pope. If all these apostles were allowed maintenance for themselves and their wives, Paul had equal right to demand that the church support his wife had he chosen to marry.]
