This is not true of all non-denominational pastors. I have a friend (since childhood) who graduated from college and seminary (therefore, he is highly educated), and spent the first 20 years of his adult life pastoring Conference Baptist churches. After much prayer and consultations with mature and faithful Christians, including pastors, he and his wife made the decision to start a non-denominational church affiliated with Rick Warren’s Purpose Driven Life.
There are many reasons why pastors and people prefer non-denominational churches. one of the main reasons is that the members and attendees are not required to chip in a percentage of their offerings to the denominational headquarters. Many churches that serve the poor or low-income people, or who are reaching out to non-Christians who aren’t even sure that there is a God, have a hard time collecting offerings to support their church, and are not the least bit interested in supporting a far-away “denomination” and ministries that they never see or benefit from.
If any Catholics here think that sounds scurvy–well, perhaps you haven’t heard this, but I’ve heard from lots of Catholics in my parish who refuse to give to the Diocesan Pledge because of various reason (most of which sound kind of silly to me). We’re hearing people say they won’t support the Diocese because of the sex crimes–I don’t see what holding back our monies will do to fix that issue. But my point is, many people don’t like to give offerings to causes that they will never see in action.
Another reason why people prefer a non-denominational church is because they mistrust traditional churches for some reason (sometimes because of a sex crime). I personally think that they are foolish to align with a non-denominational church because if an unsavory incident occurs, the victim has no one to appeal to other than the head pastor, There is no Denominational Headquarters that will come and investigate the charges.
And yes, there are quite a few non-denominational churches that have charismatic, charming pastors that are great speakers and/or musicians, and people are attracted to these places where everything is so exciting! But c’mon now, you know that there are Catholic parishes that attract more people because of a priest who is a great homilist and/or has started exciting projects and outreaches in his parish. This isn’t just a Protestant thing–the desire to be where the action is.
