First reading
My beloved, just as you have always obeyed me, not only in my presence, but much more now in my absence, work out your own salvation with fear and trembling; for it is God who is at work in you, enabling you both to will and to work for his good pleasure. Do all things without murmuring and arguing, so that you may be blameless and innocent, children of God without blemish in the midst of a crooked and perverse generation, in which you shine like stars in the world.
It is by your holding fast to the word of life that I can boast on the day of Christ that I did not run in vain or labour in vain. But even if I am being poured out as a libation over the sacrifice and the offering of your faith, I am glad and rejoice with all of you — and in the same way you also must be glad and rejoice with me.
