The crozier is a pastoral staff that is conferred on bishops (and abbots) at their ordination. In the West, the top of the staff is curved to remind the bishop of the shepherd's crook and of his pastoral care of the people entrusted to him. It is a sign of the bishop's need to keep watch over his whole flock, sustaining the weak and faltering, confirming the wavering faith, and leading back the erring ones into the true fold.
