There are 2 masses. Neither is mandatory, but the closing mass is considered part of the program. The saturday morning mass is completely optional. It is scheduled before breakfast. We simply left before closing mass. No one said anything to us about it. The priest takes a turn speaking on each subject during the presentations. Mainly he talks about marriage from what he has observed in his own family, and within his professional experience. He does not present himself as an expert on marriage, just an obvserver. I think he is there not specifically as a Catholic priest, but more generally as a Christian priest. He is also there to take confessions from anyone desiring to speak to him. Our priest was a friendly guy with an upbeat point of view. It was pleasant listening to him even if I am not Christian in belief.
