Greek original is also available side by side with the translation.

“Christ does not bless those who just teach, but those who have already worked His commands and received the Grace to see above and look in themselves the Light and the Thunders of the Spirit, thus having understood in a real vision, knowledge and energy of the Light, all that are going also to say and teach to the others. This is how, as we said, must rise those who try to teach others, so that they won’t talk about things they don’t know, deceiving and dooming themselves and those who believe their words.”
