Non-Catholics visiting a Catholic Parish and experiencing a coldness, is real, and it has more to do with Catholic Culture than anything else.
Most Catholics are cradle-Catholics, that is, they’re Baptized as infants, and raised in a Catholic parish.
For them, Sunday and Holy Day Mass attendance is mandatory, with the threat of mortal sin hanging over them.
However, when many cradle-Catholics hit their teens, they leave the Church, or attend, on an irregular basis, unless they’re still living at home and their parents make them attend. Others just continue to attend, out of the sense of obligation and conformity. A few, have a deep faith commitment.
There are some who had left the Church return, after having a religious experience and Christ comes into their life in a big way. They are all fired up, and get involved at a higher degree than many of their fellow Catholics. However, their zeal usually wanes as their prayer life deepens and they have a more of a personal relation with Christ, rather than the community aspect.
What I’m trying to describe here is, Catholic parishes consist of a wide variety of people who are at different levels of faith. The one aspect that they share in common however, is the Eucharist.
Outside of Mass, most just return home and carry on with their daily life. A few others get involved in parish ministry. This also had a lot to do with the fact that many of the baby-boomer aged Catholics, grew up in parishes where the nuns and priest did just about everything. Thats changing, but in the North East, it seems parishioners haven’t gotten the idea yet. Parish closings are becoming a wake up call for them.
If you contrast the culture, compared to a newly formed Evangelical Christian Bible Church, its night and day. The Evangelical Church is going to have a majority of people who attend, who are fired up about their faith. They attend services, because they desire it, not because they feel obligated to. As a result, the majority are sharing a same general level of faith and are involved in their parish life to a higher degree than Catholics do in their parishes.
There are exceptions, but from my 57 years of being a Catholic, this seems to be the common thread.
