I would have to say quite alot to be effective. For years in my Catholic church I didn’t know at least half of the names of the parishioners, not because I didn’t make an effort to, but because the folks were just come to mass and then go home. A very cold feeling that didn’t ever resemble Christianity much. We tried out reach type groups like The Sons of Joseph and such but never any interest. My father and I tried a couple of fellowship groups which the priest really frowned upon. Nothing ever worked. I gave up and turned Anglican. Now I am a Vestry member and my son is a stand out in his worship center groups. He goes to campouts and overnight felowships and such. My wife and I are going to attend Cursillo soon and my wife is more involved in the church than I ever thought she would be. This was never possible before.
Does being involved in so many groups make you feel close to God?
Does God look at quantity or the quality of our service to our fellow man?
I would rather be in one little group and give all my Christianly love to it, than accumulate a mass of titles, clubs, fellowship groups, committees, and campouts.
You can never be as close to God as what Catholics are, as we receive God through His Body and Blood.
The number of people you associate with does not make you a better Christian.
Jesus calls us to be humble in our worship.
I fail to see how being a stand out in a worship group fulfills the wishes of Jesus.
Attending the Catholic Mass is exactly what Jesus asked us to do.
He also asked us to feed the hungry, give drink to the thirsty, clothe the naked, give welcome to strangers, visit the sick, visit the imprisoned, and bury the dead.
None of these can be done by hanging around in the foyer at church after Mass.
They are done by Catholics through hospitals, St Vincent de Paul Societies, charities, outreach groups and so on.
We are told at the end of every Mass to go forth and spread the Good News.
That can’t be done standing in the foyer talking to fellow Catholics.
