Holy Orders is the sacrament by which a man becomes a priest.
If you are interested in exploring the possibility of becoming a priest, you might want to talk with Father Andrew. Also, you can contact the Archdiocese and ask to speak to Father John Henderson, the Vocations Director, 503-234-2334.
Or you may wish to contact particular Orders (such as the Jesuits, or Benedictines or Salesians) directly.
