Pray and ask the Lord to show you. Look for a priest who is faithful to the teachings of the Church, prayerful, seeking holiness, witnessing a life of holiness, with whom you are comfortable speaking, and can meet on a regular basis. A good confessor may be someone to consider. You might also ask someone you trust for a recommendation. When you find someone, meet a few times first to see how it works out. If you need help in deciding on a director, don't hesitate to contact the Office of Priest Vocations for assistance.
