Orthodox Christians hold to both Tradition and the Scriptures, as both are seen as coming from the Holy Spirit. Some object to idea of Tradition being on the same level as the Scriptures, but Paul twice specifically calls Christians to follow the Traditions of the church.
In the first verse, Paul encourages Christians to stand fast to the traditions passed on orally and those that were written. In the next verse, Paul uses stronger language and commands that we should withdraw from those who do not keep the traditions. In no uncertain terms, Paul states that to obey tradition in an apostolic command.
Two common objections to this are, “All the traditions that were transmitted orally were eventually written down by the time the Bible was complete” and “But Jesus has an awful lot of bad things to say about those who keep traditions.” The first objection creates more questions than it answers. However, nowhere in scripture does Jesus command that all or part of what He said should be written down. Jesus Himself never wrote anything down, except in the sand.
But what of all the negative things Jesus has to say about tradition? It is true that Jesus has much to say about those who follow tradition, but many times He is specific about what He means by tradition.
Beware lest anyone cheat you through philosophy and empty deceit, according to the tradition of men(Col 2:8)
knowing that you were not redeemed with corruptible things, like silver or gold, from your aimless conduct received by tradition from your fathers(1 Pet 1:18)
Often Jesus associates tradition with the “tradition of men.” There is a distinction between traditions of men and traditions given by the Holy Spirit. Those traditions that Paul commands us to obey come from the Holy Spirit and not of men.
Some modern scholars dislike the idea of tradition so much that they have even removed it from their bible when it suits them, specifically the NIV. The word for tradition in Greek is paradosis. It is used throughout the New Testament where it speaks of tradition as a good or bad thing. However, in the NIV, when the word is used in a positive sense, the translators have removed the word traditions and replaced it with teachings or doctrines. This is not a good practice. One should not change the words of scripture to suit their own personal ideas.
The Orthodox church remains faithful, like the early Christians to the Holy Spirit which has given us both the Holy Scriptures and Holy Tradition.
