15. This stained glass window shows Christ’s triumphal entrance into Jerusalem on Palm Sunday, celebrated annually on the Sunday before Easter. On this day, Jesus was welcomed into the city and heralded as the King of the Jews. The fact that Jesus entered Jerusalem on a donkey symbolizes a peaceful and humble arrival, rather than one of a warrior king riding a horse. Less than a week later, the same people who had greeted Him as their Lord would demand His crucifixion.
