Ben and Jennifer Garner walked out of church Sunday morning in Pacific Palisades with their son, Samuel ... their daughters, Violet and Seraphina, were there too. We've seen Ben leave rehab almost weekly now -- sometimes for a workout session, sometimes for studio meetings.

It's a different approach for sure. Typically, rehab facilities want to remove patients from their day-to-day patterns and focus on treatment. It's been about 5 weeks since Jen staged an intervention and drove Ben to rehab -- but it's unclear if he's still a patient.
