¿Cuál es la diferencia entre clero regular y el secular?

Explanation:

El clero secular es el que se ordena como sacerdote para llevar los sacramentos a la comunidad, mientras que el clero regular, es el que se aísla a servir a Dios desde sus acciones personales profesando humildad y vocación religiosa.    

ENGLISH: while regular clergy take religious vows of chastity, poverty, and obedience and follow the rule of life of the institute to which they belong, secular clergy do not take vows, and they live in the world at large (secularity) rather than at a religious institute.
