IHS and Pomegranate windows
The use of monograms to represent Jesus Christ our Lord is of very early origin. The monogram IHS stands for for the name Jesus: they are the first three letters of the word Jesus written in Greek capitals.
The monogram IHS should remind each of us of Jesus, and when we are reminded of the name Jesus, we are also reminded of the reason He came to be born of a virgin. The angel said it to Joseph when told to call His name Jesus - "for He shall save His people from their sins." (Matthew 1:21)
The pomegranate is a popular symbol of the resurrection of the Lord Jesus Christ and also of the resurrection of His faithful followers. It, therefore, symbolizes the hope of new life because it is split by the pressure of its many seeds by which is signified the fruitfulness or the power to reproduce life. The Bible says, "If any man be in Christ, he is a new creature, old things have passed away; behold, all things are become new." (2 Corinthians 5: 17) By the power of Christ's resurrection, we are raised to a new spiritual life in Christ and we have everlasting life now. So the symbol of the pomegranate should remind us of Christ's resurrection, our new spiritual life in Christ, and of our own bodily resurrection on the Last Day.
