1 Corinthians 2:15

But he that is spiritual judgeth all things The word which is used in this and the preceding verse, which is translated discernedin the last verse, in the text of this verse by judgeth, and in the margin by discerneth, signifies in every other passage in the N. T. to examine, and is so rendered by the Vulgate (see Acts 4:9; Acts 12:19; St Luke 23:14, and ch. 1 Corinthians 9:3). It must therefore be interpreted of the process rather than of the conclusion, of the exact scrutiny to which the spiritual man can subject all things, while he himself is beyond the scrutiny of others who do not possess the means of making it. "The Gospel in its essence is neither theoretic, abstract, nor reflective, nor even imaginative: it is historical, but this history is Divine. The preaching of the Gospel is a revelation of God's doings. When belief is well established, then, and then alone, may God's acts become subjects of theory or research among the members of the Church, and even then so far only as the whole investigation proceeds from faith. Of such an inquiry faith could never be the consequence. In God's Spirit alone has faith its origin." Olshausen.
