Acts 18:13 New English Translation

¹³saying, “This man is persuading^[a] people to worship God in a way contrary to^[b] the law!”

Acts 18:13 tn Or “inciting.”
Acts 18:13 tn Grk “worship God contrary to.” BDAG 758 s.v. παρά C.6 has “against, contrary to” for Acts 18:13. The words “in a way” are not in the Greek text, but are a necessary clarification to prevent the misunderstanding in the English translation that worshiping God was in itself contrary to the law. What is under dispute is the manner in which God was being worshiped, that is, whether Gentiles were being required to follow all aspects of the Mosaic law, including male circumcision. There is a hint of creating public chaos or disturbing Jewish custom here since Jews were the ones making the complaint. Luke often portrays the dispute between Christians and Jews as within Judaism.
