I've spent some time during the past two weeks, studying about the Greek Orthodox Church and, once again, I find no articles or sermons refuting their doctrine and activities. The fact that I fail to find any probably does not mean that there are none, but apparently they are few.
It first caused me to wonder why, when a church is simply split off another as it is from the church of Rome, it has not nearly the notoriety that the Roman church has. Their general doctrine and worship services are quite similar, although they have a number of mostly cosmetic differences. Their partaking of the Lord's supper is unique as is their praying. They do not kneel for long periods as the Catholics do, and find acceptable any position for prayer, from standing upright to the kneeling position (they refer to this as prostrate) and touching their forehead to the floor as the Muslims do.
And then I decided that the probable cause for the lack of writings opposing this Church is the fact that they have not been nearly as radical and aggressive as has the Roman Catholic Church. I might be totally wrong, but I have never heard of any of the scandals that have been almost constant from the Catholics. Nor have I known of any strong, aggressive movements for power and political clout as has been the habit of the Catholics. That may also be the reason for their failure to grow as rapidly as the Catholics.
It will not take the Bible Student long when reading their articles and doctrines, to see the depth of their error, but you must respect them over Catholicism for keeping their noses fairly clean, I think. Always pray for God to open doors for us, but pray even more earnestly for vision to see the ones that are already open.
