Jesus knew nothing of "Holy Orders".  That's an institutional church construct.  Jesus was familiar with His own Jewish religion's priesthood and when He was incarnated rejected being born of the priestly tribe.  He was a layman all His life.  Jesus never discriminated and never excluded.  He affirmed that we all, male and female, are made in God's image and likeness.  If the vocation of priesthood (servant-leadership) is to justly exist, then it must be open to all who hear God's call.
