Devarim 23:26

Verse 25. So also when you comest amongst the natural goods that have been developed from others of different religious creed, it is allowable to make use of the good scientifics which gave birth to those goods as external truths under the power of spiritual truth; but it is not allowable to imbibe them and make them your own, as the goods with which the Lord has endowed your own soul by the separation of good and evil within you in regeneration. [Note.—Standing corn denotes the truth of good and faith in conception. (See also Arcana Coelestia 5212.)]
