Active communities of brothers, often called friars, live and pray together, just like monks, but during the day they enter the world to directly advance the kingdom of God. Religious priests often serve in sacramental roles similar to diocesan priests, while religious brothers take on many apostolates outside of parish life: chaplains, teachers, counselors, evangelists, and minsters of the poor. While active brothers still pray frequently, they understand their mission as an important part of their prayer.
