What I find fascinating is the claim that the Letter to the Hebrews reflects this early liturgical pattern: If you look at Chapter 12, it contains a call to repentance and striving for peace with one another: ...12 Therefore lift your drooping hands and strengthen your weak knees, 13 and make straight paths for your feet, so that what is lame may not be put out of joint but rather be healed. 14 Strive for peace with all men, and for the holiness without which no one will see the Lord. 15 See to it that no one fail to obtain the grace of God; that no “root of bitterness” spring up and cause trouble, and by it the many become defiled. This prepares for the Blood and Sacrifice which unites us all on earth and in heaven: 22 ...you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, 23 and to the assembly of the first-born who are enrolled in heaven, and to a judge who is God of all, and to the spirits of just men made perfect, 24 and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks more graciously than the blood of Abel.
