A more thorough explanation:

CLERICO INFRA SACROS ORDINES CONSTITUTO NON ELIGENDO IN OFFICIUM

A Latin phrase that means a cleric who has not yet received holy orders cannot be appointed to an office.

John, a seminarian who has not yet been ordained as a priest, cannot be appointed as a bishop.

This phrase emphasizes the importance of receiving holy orders before being appointed to a higher office in the church. It ensures that only those who have received the necessary training and spiritual preparation are appointed to positions of authority within the church.
