Virtual Tour of the Cathedral of Mary Our Queen

The bottom panels (under Jesus' feet) show (left)
Mary (sister of Martha) washing and anointing Jesus' feet
with costly oils, arousing Judas' anger (John 12:1-8)
and (right)
Jesus washing the feet of His disciples during the Last Supper.

The window also shows:

Christ's agony in the garden
His scourging at the pillar
His Crucifixion
His Body being taken down from the Cross
Four panels that relate Psalm 23 to the Eucharist: 1) He leads me beside still waters; 2) Even though I walk through the darkest valley, Your rod and Your staff give me comfort; 3) You anoint my head with oil, my cup overflows; and 4) I shall dwell in the house of the Lord.
