A more thorough explanation:

BENEFICIO PRIMO ECCLESIASTICO HABENDO

BENEFICIO PRIMO ECCLESIASTICO HABENDO is a Latin term that means "having the first ecclesiastical benefice." It refers to a writ from the king to the lord chancellor, ordering the appointment of a named person to the first vacant benefice.

An example of BENEFICIO PRIMO ECCLESIASTICO HABENDO would be a situation where a king orders the appointment of a specific person to the first available benefice. For instance, if a bishopric becomes vacant, the king may issue a writ to the lord chancellor, directing him to appoint a particular person to the position.

Another example would be if a parish priest dies or retires, and the king orders the appointment of a specific person to fill the vacancy. In this case, the person named in the writ would be the first to receive the benefice.

BENEFICIO PRIMO ECCLESIASTICO HABENDO was a legal term used in medieval times to ensure that the king had control over the appointment of important church positions. The writ ensured that the king's chosen candidate would be the first to receive the benefice, regardless of any other candidates who may have been considered.

The examples illustrate how the writ was used to appoint specific individuals to vacant church positions. This ensured that the king had control over the appointment process and could ensure that his chosen candidate was appointed to the position.
