The Garner-Affleck family loves to throw a birthday party!

First it was Samuel's fourth b-day -- where Ben Affleck dressed as Batman for his son -- and now, Jennifer Garner threw quite the bash to celebrate turning 44 on Sunday, even recruiting a marching band for the occasion.

The Alias actress' day started off far more low-key though, attending church with her three children -- Violet, 10, Seraphina, 7, and Sam -- before Affleck took the kids to lunch.

As for the church outing, the Miracles From Heaven star previously opened up to ET about her own "miracle" that returned her to her faith.

"I grew up going to church every Sunday," she told ET's Cameron Mathison. "Doing this film and being around people where church was normal, more normal than it is in Los Angeles, it kind of just made me think, 'I've got to get on this.' So, I talked to my kids, and they said, "Of course, we're ready to go.'"
