I believe Salpy is refering to a defrocked priest who used to serve in Colerado. According to his own testimony (the defrocked priest testimony), he was protestant and wanted to infiltrate the Orthodox Church in Egypt by pretending his conversion to Orthodoxy and entering the theological school in Egypt. His testimony was attached as media file some time back on this forum. He was ordained priest, and a year after, he started to preach his poisonous protestant teachings in which he denied the sacraments. He was defrocked, anthamized after two rounds of apparent repentence and returning to his old ways. He was anathemized permanently afterwards. His ugly trick was dismissed by him and by his interviewer on the Lutheran radio broadcasting channel as the only way to infiltrate the Coptic Church. Very dirty.
Individuals such as this priest and other example along histories should not be a cause for worries, as long as they are defrocked and excommunicated. Yet what is a cause of great distress are such unorthodox practices such as allowing people with protestant tendencies to preach in the church and not taking tough stands against it. Specially in the West, the kids grow up in a very evangelical and protestant (or atheist) influenced society and they tend to have a group hug mentality that embraces all ideas and rejects none. This lack of discernment made the church service depend mostly on immigrants with a more conservative background, yet with other problems such as language. It is a tough challenge.
The churches in Egypt do not suffer from such problems because of the overwhelming presence of Orthodox. The Protestant missions that get financial support from many organisations started out trying to convert muslims, yet due to the difficulty of such mission, they targeted the Orthodox where they do not have to deal with apostacy from the government, and do not have to struggle with dogmas such as trinity, Incarnation, .... .
The obvious remedy is intensive teaching to the whole congregation about Orthodoxy. In the West, I rarely hear anything in mass or general sermons about the necessity of the Apostolic Faith for salvation. I am all for spiritual sermons, but without proper basis in Orthodoxy it is in vain. How can repentence be accomplished without proper understanding of the confession sacrament, and how can the person be assured of savlation if he does not know why we partake in the Body and Blood of Christ. Unfortunately, in some churches, these topics are considered only for theologians, which is not true.
The next step would be to cut any unorthodox branch off from service if repeated advice does not bring fruits. We cannot afford to leave such tendencies in our church. I was shocked and furious to know that a church was using the "40-day thing" by Rick Warren in their service meeting. I was more shocked that such practice went unnoticed by the servants themselves for many weeks, until a friend told the bishop and he took action ( a severe one ). We have by far better books to deal with servants that have been very successful, why the need to go to unorthodox sources ?
There is a great difference between an inquirer about faith and between somebody who tries to change the faith from within the church. The latter can do so outside the church under any title they want, but not under the umbrella of the Orthodox Church. The former are most welcome. This fine line (not that fine) has to be discerned.
