E-collection basket – Parish cashless electronic giving seen as growing

It's a new technology for the Catholic Church. People certainly have to be good stewards of their money to use it though. Plastic cash, be it credit cards or debit cards that can access lines-of-credit, has led a lot of people into serious financial difficulty. I'm sure the Church doesn't want to be part of that. Financial teaching, teaching about being responsible stewards of what God gives us financially, has not ever been a big part of Catholic education. Sermons from the pulpit about giving to the Church have even been few and far-between these days.
