Unfortunately, because of the times we live in, our first tip is that of caution and prudence. We must always be careful of who we allow to enter our home.

But how can you know if they are from the Church of Latter Day Saints? 1) They always travel in pairs, so if there is a single individual at your door claiming to be a missionary,do not trust that. 2) The Mormon Missionaries are always assoicated and supervised by the local church, so you can call the nearest church (or Ward as they refer to their area) and verify that they are missionaries. After you have come to the decision that they are indeed Mormon missionaries and you are willing to invite them in, then our suggestion is to go ahead.

Pope John Paul II be to hear that question? What a great example of 'the new evanglization.' Let me first give some stories of young people evangelizing and then some practical examples.
