Yes.
It's quite possible not to be a formal believer, but value the ritual, ceremony, history, community, fellowship... which comes with religious behaviour.
A true believer might be uncomfortable with that idea, but people can be comforted by the familiar, the ancient and the communal independently of an actual belief in the words spoken.
Sometimes the *less* the words and rites are understood, the more powerful the effect is. This is where "tradition" can become the focus simply because it's tradition. Not the King James or the Latin Mass because it's theologically superior* but because it's older, more evocative.
*A genuine but different belief about the same objects, for some.
Two people next to each other at a service may be doing, and understanding, very different things.
