So many feasts of the apostles are lumped into the Easter Season - fitting of course as they give everything for the message so real and important to them.
In this crowd, it is James we know the most about; related to Jude and Jesus, and head of the Church in Jerusalem, we know of his martyrdom. Philip's fate is lost in obscurity. What we know so well from the Gospels is that Philip often seemed to miss the point of things and we get Jesus' almost exasperated responses. But it is Philip's role to bring the Greek believers to Jesus and for that we celebrate him.
Brothers in the Lord, it is only the happy coincidence of the transfer of the relics to Rome on the same day that brings their feasts together.
Jesus said to Thomas, "I am the way and the truth and the life.
No one comes to the Father except through me.
If you know me, then you will also know my Father.
From now on you do know him and have seen him."
Philip said to him,
"Master, show us the Father, and that will be enough for us."
Jesus said to him, "Have I been with you for so long a time
and you still do not know me, Philip?
Whoever has seen me has seen the Father.
How can you say, 'Show us the Father'?
Do you not believe that I am in the Father and the Father is in me?
-- John 14:6-9
