Revised Common Lectionary (Complementary)

The Pharisees seek a sign. Jesus warns his disciples of the Pharisees’ doctrine. Peter’s confession. The keys of heaven. The faithful must bear their cross after Christ.

16 Then the Pharisees and Sadducees came and tempted Jesus, asking him to show them some sign from heaven. ² He answered and said to them, At evening you say the weather will be fair, and that because the sky is red; ³ and in the morning you say it will be bad weather today, and that because the sky is cloudy and red. O ye hypocrites, you can discern the aspect of the sky, and can you not discern the signs of the times? ⁴ The froward and adulterous nation seeks a sign, but no other sign shall be given to them than the sign of the prophet Jonah.

So he left them, and departed.
