Test all things, and hold firmly that which is good.
In the Apostolic Age, the means of testing those things that purported to come from God existed in those who had been endowed with "the discerning of spirits" (1 Corinthians 12:10; 1 Corinthians 14:29; 1 John 4:1). "Another sure test, which we also have, is, to try the professed revelation whether it accords with Scripture, as the noble Bereans did (Isaiah 8:20; Acts 17:11; Galatians 1:8-9)" (Jamieson, Fausset, and Brown 392).
