Here’s an excerpt from big words and windows, a post by Fr John O’Connor, a Catholic Priest in the diocese of Christchurch, NZ.
The language we use in church is often an obstacle for good people. A sermon flowing with words like adoration, beatific vision, catechesis paschal mystery and dogma may be thoroughly orthodox and inspiring to the theologian, but it will probably not touch the hearts of the worshippers at a parish Sunday Mass.
These big words are important since they are the windows to essential knowledge of our faith. The big words are our linguistic short-cut, our method for conveying all that scripture and tradition teaches us about each aspect of our faith.
Therefore it is important that when we use these words, we also provide the meaning in an understandable, accurate and attractive form. At times, for a particular audience, we might speak about (for example) the “incarnation,” without using the word itself. Our hope is that with good catechesis there will come a time when the simple use of this big word will remind the hearers of the full meaning of the incarnation of Jesus. The word will be the window leading us to recall the full significance of the event of the incarnation.
