(I apologize in advance if this question isn't appropriate for Christianity S.E. .... this seems to be a trending problem. With that said, I believe the ideas of the question are appropriate and I invite anyone that thinks this question is inappropriate to edit it so it's rephrased more appropriately).
From my experience, many visitors at churches feel that they need to give money and most churches (not all) do this by passing a collection plate of some sort, this method seems to even embarrass or coerce visitors into donating to the church. I feel that the people that should give their money are regular visitors that genuinely want to help the church (regardless if they are believers or not) and members. The reason I think this post is important is because I kind of find it strange when attendance balloons two days out of the year, as does the collection; plus, I think it is discouraging for the average new visitor. Specifically, I am looking for scripture that will support or refute the claim that the method by which most churches collect money is un-Biblical at worst and awkward at best.
