GREEKS, GRECIANS.?Both these terms are used indifferently in AV of OT Apocr. to designate persons of Gr. extraction (1Ma_1:10; 1Ma_6:2; 1Ma_8:9, 2Ma_4:36 etc.). In NT the linguistic usage of EV makes a distinction between the terms ?Greeks? and ?Grecians.? ?Greeks? uniformly represents the word Hell?n?s, which may denote persons of Gr. descent in the narrowest sense (Act_16:1; Act_18:4, Rom_1:14), or may be a general designation for all who are not of Jewish extraction (Joh_12:20, Rom_1:16; Rom_10:12, Gal_3:28). ?Grecians,? on the other hand (Act_6:1; Act_9:29), is AV tr. of Hell?nistai, which means Gr.-speaking Jews (RV ?Grecian Jews?). See preced. art. and Dispersion. An interesting question is that of the correct reading of Act_11:20. Were those to whom the men of Cyprus and Cyrene preached, Grecians or Greeks? In other words, were they Jews or Gentiles? The weight of MS authority is in favour of ?Grecians,? but it is held by many that internal evidence necessitates ?Greeks.?
