It's not only the Christian denominations that are avid in their recruitment but Muslim are also at it - they say that getting a convert will reserve you a slot in heaven, so to speak. On the other hand, the Catholic church seems to be doing nothing about it. Some Christian sects are having a success in getting Catholics to be converted to their religion.
In my mind, I think the church has to change some policies to be abreast with the times. And they should be strict in implementing the traditional practices of the church by not giving too much freedom to the priests. Where before the holy mass takes less than an hour, now it is always more than an hour because of the caprices of the parish priest.
