Proselyting to non-Christians (which should include Mormons,Jehovah Witnesses, Christian Scientists etc) is encouraged. Doing so to Christians whose baptism can be accepted by economia (RC, mainstream Protestants, etc.), it is prefered that proselytizing be done by witnessing (which is the better way of preaching anyway).
It is also better to cultivate a relationship that is inviting, rather than handing them a tractate.
Greetings in that Divine and Most Precious Name of Our Lord and Savior Jesus Christ!
Amen Amen, goodly words there my brother. Witnessing is exactly and precisely what Christ has called us to be and do, and it is the only work of the Apostles, who are the witnesses of His Resurrection and Life. And practically, it cultivates a better relationship and invitation than the boring, self-righteous activities we call "preaching" as a form of evangelism. Preaching is for believers and sermons.
The Bible Thumpers of the world should take note of your humble suggestions
To spread the truth of the Orthodox, we must simply live our Orthodox lives in the midst of all the people, and demonstrate effectively how the Divine Mysteries and the Holy Tradition are always operating in our lives towards healing and salvation, and that only the Orthodox offers the purest renditions of God's economy of Grace on the earth.
the cultural and linguistic issues are something which must be taken with a great deal of consideration by the way. I often have people ridiculously excited to come to my Ethiopian parish with me, because they see how great God is operating in my life, but I actually turn them away, because I can see that they are not grounded enough in what to expect, and actually to take them to a Mass so thoroughly unprepared might actually be harmful! They may understanding the rituals, the icons, the incense, the prayers and get confused, especially here in the US with such a prevalent protestant background which has imbedded a demonizing of anything even remotely Catholic! Our Lardy the Virgin actually frightens many Americans, as do vestament clad priests chanting inaudible incantations! Worst of all, at times Americans, selfish as we are, assume EVERYBODY in the world just HAS to speak English, and many Americans actually feel antagonized and insulted when confronted with religious services in a 'foreign' language, where as in Orthodox this is fundemental to the Orthodox experience, as in most histories and places of Orthodox, from Egypt to India, from Romania to Russia, the Church prays in languages never spoken on the street. We in Orthodox are accustomed to linguistic adjustments, where Americans often misperceive such as a kind of linguistic cheuvenism! These are serious obstacles which must be overcome, slowly, patiently and in good faith and love. We must show people HOW these Orthodox lifestyles change and benefit our lives, not just show them the Orthodox as it is at face value. This can be very discouraging both for potential visitors and for Orthodox faithful who enjoy sharing their faith..
