The Church teaches us to understand the Scriptures through the lens of Church Tradition.
113 2. Read the Scripture within "the living Tradition of the whole Church". According to a saying of the Fathers, Sacred Scripture is written principally in the Church's heart rather than in documents and records, for the Church carries in her Tradition the living memorial of God's Word, and it is the Holy Spirit who gives her the spiritual interpretation of the Scripture (". . . according to the spiritual meaning which the Spirit grants to the Church"81).
This has been very helpful to me in understanding the Word of God. But more recently, I've learned to look at the New Testament through the lens of the Sacraments. There are so many verses which we can't understand completely unless we recognize the Sacraments. I was reminded because today at Mass, the first reading said:
1 Pt 1:10-16Do you recognize the Mass in this reading? It's in these words.
Beloved:Concerning the salvation of your soulsthe prophets who prophesied about the grace that was to be yourssearched and investigated itinvestigating the time and circumstancesthat the Spirit of Christ within them indicatedwhen it testified in advanceto the sufferings destined for Christand the glories to follow them.It was revealed to them that they were serving not themselves but youwith regard to the things that have now been announced to youby those who preached the Good News to youthrough the Holy Spirit sent from heaven,things into which angels longed to look.
Therefore, gird up the loins of your mind, live soberly,and set your hopes completely on the grace to be brought to youat the revelation of Jesus Christ.Like obedient children,do not act in compliance with the desires of your former ignorancebut, as he who called you is holy,be holy yourselves in every aspect of your conduct,for it is written, Be holy because I am holy.
Therefore, gird up the loins of your mind, live soberly, and set your hopes completely on the grace to be brought to you at the revelation of Jesus Christ.Unlike the Protestants, we are not simply awaiting Jesus Christ at the Second Coming. We, who understand our faith, are yearning for Christ revealed to us on the Altar, in the Mass, in the Holy Eucharist.
