2:8 James did not mean Christians should avoid honoring the rich but that we should love everyone and treat every individual as we would treat ourselves (Matt. 7:12; cf. Lev. 19:18). The "royal"(Gr. basilikos) law is royal in that it is the law of the King who heads the kingdom (Gr. basilikon) that believers will inherit (v. 5).90It is also royal in that it is primary; it governs all other laws dealing with human relationships (Matt. 22:39; cf. Lev. 19:18). Moreover it is "conduct of a high order that is worthy of a king."91
2:9 In this verse James used the verb form of the same Greek word he used in verse 1, namely, prosopolepteo. The type of preferential treatment James dealt with in this pericope (2:1-13) violates the royal law because it treats some as inferior and others as sources of special favor (cf. Acts 10:34). It also violates specific commands found in God's Word that reveal God's will in interpersonal dealings (Matt. 7:12; cf. Lev. 19:15).
"The passage calls us to consistent love, not just polite ushering. People of low income are to be fully welcomed into the life of the church. The passage calls us to be blind to economic differences in how we offer our ministries. The poor person is as worthy of our discipling and pastoral care and love as the person who has the means to rescue our church from its budget crisis."92
"Anyone who shows favoritism breaks the supreme law of love for his neighbor, the law that comprehends all laws governing one's relationships to one's fellowmen."93
