Celebrating the Paschal Mystery in the Liturgy

From that time onward [of the apostles] the Church has never failed to come together to celebrate the paschal mystery, by reading what was written about him in every part of Scripture, by celebrating the Eucharist in which the victory and triumph of his death are shown forth, and also by giving thanks to God for the inexpressible gift he has given in Christ Jesus, to the praise of God's glory.

I always think of the first and second readings as being there to open up and eludicate what comes in the Gospel reading. I somehow never thought of it in the words used above — that these readings are seen as being specifically about Jesus. 

On the one hand, well duh! On the other, well I never! I love how there is always more to learn that opens our eyes and hearts. And how deeply the Church gives us opportunities on every level to encounter Christ.
