Missionaries and churches have sometimes taken the approach that languages are a barrier, refusing to use them for worship or evangelism. Instead they use a regional, dominant, or official language. Dr. Harriet Hill and Dr. Lamin Sanneh have pointed out that this often leads to stagnation of the Christian faith.
It has become more and more common for missionaries to see languages as a bridge rather than as a barrier. In fact, seeing languages as a bridge has become so common that we can speak of a paradigm shift in missions. One very large international mission agency even shifted all of its work away from dominant languages to local languages when the saw the success of the latter approach.

Unfortunately churches lag behind missions in this paradigm shift. Their members may have a vested political economic, educational, tribal, or other interest in maintaining the dominant language. Also they are generally not aware of the successes of ministry based on the idea that every language is a bridge between the people and the Gospel.
In Ghanaian churches we sometimes encounter skepticism of the value of translating the Bible into the lesser known languages of the country. If the problem is that they lack information, they quickly change their minds once they are informed. On the other hand, things are more difficult if they have a vested interest in maintaining the dominant language. Language is often highly political.
So, our goal of mobilizing the churches in Ghana for translation addresses both the need for information and the need to moderate some political positions.
