Difference between ministerial priesthood from priesthood of the laity?

something that has to do wit Romans laws

Roman Catholic AnswerPriesthood implies sacrifice, the Ministerial priesthood is set aside by God through the ordination by the Bishop to stand in the person of Christ and offer His Body and Blood in sacrifice to the Father in Heaven. But, all Catholics are called to priesthood through their baptism. If you read Romans 12:2, you see St. Paul explaining this priesthood. The priesthood of all believers also offers sacrifice, as St. Paul says, we offer our body as a living sacrifice holy and acceptable to God, your spiritual worship. An entire article explaining this is given in the link below. We are called to consecrate our whole lives, whatever we do, whatever we eat, etc. all for the glory of God.
