Canon 8
In the eighth discussion we discovered that some people obligated to celebrate the Divine Office are so full of negligent ignorance, that they are not competently informed about the order of prayers for everyday use. Hence, we diligently decide and decree that from now on, a person who does not know the psalter, usual canticles and hymns, and the rite of baptism shall not be ordained to the dignity of any ecclesiastical grade. And those who already have an honourable dignity, but are vexed by such blindness of ignorance shall voluntarily devote necessary effort to learn or, if they are not willing, they shall be compelled to the exercises of lecture by their superiors.
