[3:20] 1 tn The meaning of this verse is disputed. According to BDAG 634 s.v. μεσίτης, “It prob. means that the activity of an intermediary implies the existence of more than one party, and hence may be unsatisfactory because it must result in a compromise. The presence of an intermediary would prevent attainment, without any impediment, of the purpose of the εἶς θεός in giving the law.” See also A. Oepke, TDNT 4:598-624, esp. 618-19.
