In this stained glass window above the altar on the left we see Mary and on the right St. John.

When Jesus saw his mother and the disciple there whom he loved, he said to his mother,
"Woman, behold, your son."
Then he said to the disciple, "Behold, your mother."
And from that hour the disciple took her into his home.
(Jn19:26-27)
