Tentatively Christian; looking for a reasonable discussion

Religious attendance/participation is a positive determinant of health (categorised by happiness and longevity), recognised by psychiatry and by W.H.O. It doesn't have to be true to be helpful...

You know, I can absolutely see that in some circumstances! If it's a positive experience, participation and community, it sounds plausible that it has these positive effects.
It may be statistically true, but may not be true in many individual's case. It may be correlated with other things. For all I know, people with bad (mental) health simply
participate less and there's in some cases no causal relationship.
