So now its decision time. What do these three windows mean? Here are some conclusions gathered from your comments and from my resource books. There were no difinitive guesses but you did help me shed much light on the mysteries of these windows.
To begin, what is that green thing at the bottom of this first window? I was standing in the hallway at the time when a lady in the parish said rather matter of factly, "Those are figs" as though it was the most obvious thing in the world. But you know what? It seems to make sense. The most common perception is that this first window has to do with things of the Old Testament. So let's try to sew the whole thing together. A snake (or serpent) is obviously something to do with evil. Let us suppose for the moment that it is the devil from Genesis. A torch (when it is not representing Christ or the Church as the light of the world) is a symbol of betrayal for Judas came after Jesus with "lanterns, torches, and weapons." Figs are often substituted for the apple when symbolizing the fall of man because "they sewed fig leaves together for clothing." The scroll represents the Old Testament and in the dove seems to represents the action of God throughout the church windows.
Finally here we have the Gospel book and a lamp which is most often a symbol of wisdom and piety. The dove is once again the action of God in the world.
So here is what I am thinking (wink'n and nod.) At the least the three window represent the three major stages of our faith: before Christ, at the time of Christ, and the world after Christ. We could take it a bit further and say the state of man mired in original sin, redeemed by Christ, and now living in Christ. This might work since it is also just down the hall from what used to be the baptismal font.
Anyway that is what I think. With this final bit of information if you have any other ideas please let me know otherwise this is what I am going to put in my description of the symbolism of the parish. Thanks for the help!
Now, here is a mystery that finally figured out but I'll give you a week to guess. This one I am sure of.
I presented this a couple of years ago and nobody could figure it out. It is obvious that these shelves were added later in the history of the parish. Sticking out under the top shelf is a green marble block obviously built into the wall at about mid thigh. It has an indentation at the top like a holy water font for dipping you finger in only that unless you are five years old, one would have to bend pretty far over to do so. Nobody has been able to figure this out. The best guess was that is was for people in wheelchairs but that doesn't make any sense since this door only had a ramp installed years after the building was built.
This past year I discovered this! It is on the opposite side of the wall in the confessional (not where the priest sits but where the penitent is.
