Taking on the job as a member of a parish pastoral council or board is not one to be taken lightly. You were picked neither to be a sycophant for the parish priest nor to line your pockets with the praises and the dignities of such an office. You were given this office by God to function as a type of elder who is responsible, in a lesser way, to shepherd the Church.
Employing 1 Titus 6-9 here, you must be "above reproach as God's steward not self-willed, not quick-tempered, not addicted to wine, not pugnacious, not fond of sordid grain, but hospitable, loving what is good, sensible, just, devout, self-controlled..."
In other words, your job is a sacred duty in the Church. Take it seriously. Treat your priest with respect. Get him help when he needs it. Do your part to lead the people of the Church to Christ. Watch your own household. Make sure it is not filled with the evil one. Give your life over to prayer. Give the bishop an honest assessment of the work being done or not done there.
Be humble.
Be vigilant.
Be not afraid!
