No idol is anything in the world (ouden eidwlon en kosmwi). Probably correct translation, though no copula is expressed. On eidwlon (from eido), old word, see on Acts 7:41 ; Acts 15:20 ; 1 Thessalonians 1:9 . The idol was a mere picture or symbol of a god. If the god has no existence, the idol is a non-entity. This Gentile Christians had come to know as Jews and Jewish Christians already knew. No God but one (oudei qeo ei mh ei). This Christians held as firmly as Jews. The worship of Jesus as God's Son and the Holy Spirit does not recognize three Gods, but one God in three Persons. It was the worship of Mary the Mother of Jesus that gave Mahomet his cry: "Allah is One." The cosmos, the ordered universe, can only be ruled by one God ( Romans 1:20 ).
