CHRISTOLOGY with Fr. William



10-Week Class held on Wednesdays and Fridays

from 7 to 8:15 p.m.

Who, and what, is Jesus Christ? Is the Christ of faith the same as the Jesus of history?

This course will be an introductory expedition into these and other questions, as a means of coming to know the content of our faith in Jesus Christ better. In-person class will be held outside by the school flagpole. Reservations are required for attending class in-person. Space is limited for in-person class. 

CDC guidelines will apply.

This course is designed for candidates for the diaconate in the Diocese of Orange and their wives, but it is equally suitable for anyone interested in deepening their knowledge of the Catholic faith. Therefore, we are offering spots for 40 additional people to attend in-person. Classes will be held outside by the school flagpole and online on YouTube.

NO reservation is required for watching this class on YouTube.

RESERVATION IS REQUIRED to attend the in-person class by the school flagpole.

Tickets are available on Eventbrite starting December 28 at 10 a.m.
