Liturgical Colour : Purple/Violet or White (Our Lady of Guadalupe)
Matthew 21 : 23-27

At that time, Jesus had entered the Temple and was teaching, when the chief priests, the teachers of the Law and the Jewish authorities came to Him, and asked, “What authority have You to act like this? Who gave You authority to do all this?”

Jesus answered them, “I will also ask You a question, only one. And if you give me an answer, then I will tell you by what authority I do these things. When John began to baptise, was it a work of God, or was it merely something human?”

They reasoned out among themselves, “If we reply that it was a work of God, He will say, ‘Then why did you not believe him?’ And if we say, ‘The baptism of John is merely something human’, we have got to beware of the people, for all hold John as a prophet.” So they answered Jesus, “We do not know.”

And Jesus said to them, “Neither will I tell you by what right I do these things.”

Mary then set out for a town in the hill country of Judah. She entered the house of Zechariah and greeted Elizabeth. When Elizabeth heard Mary’s greeting, the baby leapt in her womb. Elizabeth was filled with Holy Spirit, and giving a loud cry, said, “You are most blessed among women, and blessed is the Fruit of your womb! How is it that the mother of my Lord comes to me? The moment your greeting sounded in my ears, the baby within me suddenly leapt for joy. Blessed are you who believed that the Lord’s word would come true!”

And Mary said, “My soul proclaims the greatness of the Lord, my spirit exults in God my Saviour!”
