frankiespeakin regarding your question:
In the Christian Orthodox Church we don't condemn other dominations. Indeed there are some Protestand Groups that they are very heritical(like JW's, and Mormons)
The basic it is to accept Jesus as your saviour, and Jesus as God. The Trinity it is the most basic believe for the Christian faith, and this it was set by the early Church Fathers in the 3rd century, when the Trinity dogma was under question by the Bishop Arios. That is why we called those who don't accept the deity of Jesus and Trinity Arians.
By no means we as Orthodox Church we condemn to everlasting destruction those who are not Orthodox or they will end up in hell. In Church hell is considered a spirutual situation, and does not mean that God will burn someone in the flames of Hell. Hell it is to be away from God and this a atornement, like the rich guy and Lazarus in Jesus parable . God will judge each of us PERSONAL according to our actions. Since he is a loving God he examines our heart,and knows our true motives. And either you are Christian, or a muslim, or Hindu or anything, God examines our heart. If someone is a Christian does not save him/her automatically. Maybe a non Christian could have a better judgement from a Christian due to the fact that it was a person of good acts of faith.
That is why we strongly believe that God is a loving God and at the end with His Grace all will be saved.
