Pope Innocent III

“ For according to the testimony of Truth, "every one that doth evil hateth the light and cometh not to the light, that his works may not be reproved. But he that doth truth cometh to the light, that his works may be made manifest: because they are done in God." ”

“ Laymen should not preach, nor organize secret assemblies, nor find fault with priests. (Issued at the Lateran.)
Since, according to the duty of apostleship assigned to us, we have become, as the Apostle says, debtors "to the wise and to the unwise" [1] , we are required to be concerned for the salvation of everyone, so that we may both lead back evil men from their vices, and foster good men in their virtues. There is, then, need for greater discretion, when vices enter secretly under the guise of virtues, and the angel of Satan deceitfully transforms himself into an angel of the light. ”

“ But although the desire to understand the divine Scriptures, and, according to the Scriptures themselves, the zeal to spread them, is not forbidden, but is rather commendable, nevertheless the arguments against it appear well-deserved, because those who do not adhere to such arguments celebrate their assemblies in secret, usurp for themselves the duty of preaching, mock the simplicity of the priests and reject their community. ”
