Chris Pratt and Katherine Schwarzenegger Take His Son Jack, 6, to Easter Mass

Chris Pratt had a lot to be thankful for over Easter weekend.

The 39-year-old actor was spotted at Easter mass on Sunday with fiancée Katherine Schwarzenegger, 29, and his 6-year-old son Jack with ex-wife Anna Faris. The trio were seen at St. Monica Catholic Church in Los Angeles all dressed up for the morning service before spending time with Katherine’s dad, Arnold Schwarzenegger.

Pratt and Schwarzenegger announced their engagement at the beginning of the year. From the start, faith has played a large part in their relationship. A source previously told PEOPLE that Pratt was initially attracted to Schwarzenegger’s strong spirituality.

“They’re very compatible and have a lot in common,” said the source. “Family is very important to both of them, as well as their spirituality.”

Another source recently told PEOPLE that they’re on the same page about keeping their nuptials small.

“Chris and Katherine’s wedding will be a very intimate affair with just their closest loved ones,” the source said. “They don’t want it to be a circus. The focus will be their commitment to each other, and God will play a very large role on their big day. It’s been such a special time not just for them, but also for their families. Everyone is so excited.”
