For the MANY centuries when being a church person was popular and socially rewarded, this was very common. And there wasn't anything else to do. TODAY, in this post-Christian world, I don't think this is much of a problem. Well, maybe in small town, rural Texas but not in most of the world.
I've read that for converts, the # 1 reason they FIRST attend church is social... they long for community, for relationships, for friendships... and in this very isolating and technical world, that's not easy to find. Relatives likely live far way.... folks rarely even know their neighbors much less are friends with them.... people at work change often .... we build nice big walls between houses... But we are a very social species. And for SOME (SADLY, not most anymore), the church is seen as a welcoming/embracing community. I've read the #1 reason why the first-time visitor comes is in hopes of finding community.... and the # 1 reason they return is NOT good music or inspirational worship or fancy pastor but because they felt embraced and welcomed.
IMO, this is a great opportunity! Including for small churches (as over 90% of US churches are) since it SHOULD be easier for a small church to be genuinely welcoming and a community (SHOULD be, often is not). Now, the mission is not to STOP there, to simply be a social club.... As we preach and teach, we have an opportunity to not only welcome them into the community of our parish but the Communion of Saints, the one holy catholic church, the community of believers. That may take some time.
