Today is the Fifth Sunday of Lent.
At Masses where R.C.I.A. catechumens are present, today's Gospel reading will be the powerful account of the raising of Lazarus. For that passage, visit my 2008 post for this Sunday.
At other Masses, the Gospel will be a discourse of Christ exploring His role in salvation history.
From John Chapter 12:
Some Greeks who had come to worship at the Passover Feast came to Philip, who was from Bethsaida in Galilee, and asked him, "Sir, we would like to see Jesus."
Philip went and told Andrew; then Andrew and Philip went and told Jesus.
Jesus answered them, "The hour has come for the Son of Man to be glorified. Amen, amen, I say to you, unless a grain of wheat falls to the ground and dies, it remains just a grain of wheat; but if it dies, it produces much fruit.
"Whoever loves his life loses it, and whoever hates his life in this world will preserve it for eternal life. Whoever serves me must follow me, and where I am, there also will my servant be. The Father will honor whoever serves me.
"I am troubled now. Yet what should I say? 'Father, save me from this hour'? But it was for this purpose that I came to this hour. Father, glorify your name."
Then a voice came from heaven, "I have glorified it and will glorify it again."
The crowd there heard it and said it was thunder; but others said, "An angel has spoken to him."
Jesus answered and said, "This voice did not come for my sake but for yours. Now is the time of judgment on this world; now the ruler of this world will be driven out. And when I am lifted up from the earth, I will draw everyone to myself."
He said this indicating the kind of death he would die.
A Concord Pastor has a good homily on this Gospel.
And, here is a video reflection on the passage:
