I have attended Masses where the gathering was akin to family, but most are not.  In most Catholic churches, Mass is a gathering of people who happen to be there at the same time.  There is little to no interaction with anyone whom people do not previously know.  Few people stay after Mass to talk with each other.  Few become aware, let alone make connection with any who are "struggling financially, as well as socially with divorce and estrangement, addiction and suicide".
