1Cor 9, 3-5 Do we not have the right to eat and drink?

(1Cor 9, 3-5) Do we not have the right to eat and drink?

[3] My defense against those who would pass judgment on me is this. [4] Do we not have the right to eat and drink? [5] Do we not have the right to take along a Christian wife, as do the rest of the apostles, and the brothers of the Lord, and Kephas?

(CCC 500) Against this doctrine the objection is sometimes raised that the Bible mentions brothers and sisters of Jesus (Cf. Mk 3:31-35; 6:3; 1 Cor 9:5; Gal 1:19). The Church has always understood these passages as not referring to other children of the Virgin Mary. In fact James and Joseph, "brothers of Jesus", are the sons of another Mary, a disciple of Christ, whom St. Matthew significantly calls "the other Mary" (Mt 13:55; 28:1; cf. Mt 27:56). They are close relations of Jesus, according to an Old Testament expression (Cf. Gen 13:8; 14:16; 29:15; etc.).
