The windows shown are considered in three groups. In the first group, identified with Roman numerals I-III, are the big windows created for this new church building, These windows bring images of times in the lives of Jesus, Mary and Joseph who lived thousands of years ago in Palestine together with images of holy ones who lived in later times and places. In the second group are the smaller windows from our original church building, separated here but shown in four groups of three in the church. In the third group are the windows in the back of the church. These windows show Mary and St. John the Evangelist, given to each other by Jesus as mother and son, members of a spiritual family that invites, reaches out and offers to embrace each one of us.
                 
Many of those shown in these windows are seen with a halo or nimbus. The most sacred form of a halo, a cruciform halo with one vertical and two horizontal spokes, is usually applied only to images of God, such as around the head of Jesus or symbols for Jesus such as the Lamb of God. The cruciform halo appears less often in connection with symbols of God the Father or God the Holy Spirit. Where an aura is portrayed around a whole figure as it appears around Jesus in the "Universal Call to Holiness"window, "it is known as an 'aureole' or 'mandorla.' The mandorla tends to be used for particular manifestations of God's power, such as the Transfiguration, Ascension, or Second Coming." [Richard Taylor.  How to Read a Church.]
