Ekottaragama (Sanskrit fragments) 50.8.19

50.8.19

諸比丘對曰：「唯然，世尊！不聞如來說婬無罪。所以然者，如來無數方便說婬之穢污。設言無罪，此義不然。」

The monks replied, “Indeed, Bhagavān. We have not heard the Tathāgata teach that lust is no transgression. The reason is that the Tathāgata has explained the defilement of lust in countless ways. If someone says it’s no transgression, that wouldn’t be true.”
