The constant teaching of the Fathers of the Church affirm
the role of Orders or Ordination in the sacramental system
and in the life of the Church.
Didache, Ch 5, Syria, 70-110
Elect therefore for yourselves bishops and deacons worthy
of the Lord, humble men and not covetous, and faithful and
well tested; for they also serve you in the ministry of the
prophets and teachers. Do not therefore despise them, for
they are the honored men among you along with the prophets
and teachers.
