"lukewarm in religion," 1560s, from Laodicea, Syrian city (modern Latakia) whose early Christians were chastised in the Bible for indifference to their religion [Rev. iii:14-16]. The city is said to be named for the 3c B.C.E. Syrian queen Laodice, wife of Antiochus II.[Laodicean etymology, Laodicean origin, 英语词源]
