In the Orthodox Church today there are many converts from Protestantism. They have seen in Orthodoxy that which they found lacking in their former Protestant experience, but very often they speak and act in very Protestant ways still.
Does this mean that a convert from Protestantism can never really become authentically Orthodox? I sure hope not. What it does mean however, is that we have a more difficult road ahead of us then would a convert from paganism.
Former Protestants have the advantage of being more familiar with the Scriptures, and knowing much of Orthodox terminology, but often they do not move beyond their Protestant understanding of these things to an Orthodox one, or else they revert back to it at times in a pinch.
The convert from paganism, doesn't think he has already understood something that he has not -- and so is more easily instructed.
What converts must realize is that they must become white belts in the Orthodox Church -- regardless of whether or not they had been 5th degree black belts in Protestantism.
Firstly, we look to the Saints as our examples. Be ye imitators of me, even as I also am of Christ (I Cor. 11:1), the Saints say to us along with the Holy Apostle Paul. As Christians, we want to grow in the likeness of Christ, to have that likeness shine in us. For this to occur, we need to look often to the Saints to see that shining likeness: we must look to them for real, practical examples of how to live. St. Basil the Great gives this analogy: "Just as painters, in working from models, constantly gaze at their exemplar and thus strive to transfer the expression of the original to their own artistry, so too he who is eager to make himself perfect in all kinds of virtue must gaze upon the Lives of the Saints as upon statues, so to speak, that move and act, and must make their excellence his own by imitation."
Secondly, we must look to the Saints as our heavenly friends, as our brothers and sisters in the Faith, and as our preceptors. We read about them not as people who are dead, but as people who are living. And this is even more immediate than just reading a biography about someone who is still alive. Let's say we are reading the biography of some famous living person. As we read it, we may dream of perhaps one day meeting this person, or perhaps of writing him a letter and having it actually reach him, and even of receiving a reply from him,
Orthodox Christianity is unique in many ways, especially to someone who has never experienced this ancient faith. One of the things that makes us unique is the way in which we worship. How one worships is usually rarely considered or is even deemed unimportant in many faiths, but in the Orthodox Church, the way in which the people worship is very important and can be seemed as a little different to the untrained eye. We are different because we employ all five senses in almost every service, and this idea of worshiping with all our senses has been around since the beginning of the Orthodox Church almost 2,000 years ago and its practices were fine-tuned with the completion of the Bible.
