The last remaining objection to women's ordination to the priesthood rests on the belief that only twelve men were present at the Last Supper and empowered to re-enact the sacrifice in his name. On this the Church bases its decision not to ordain women, and the subsequent tradition of only appointing men to preach and teach and rule. This is the sole remaining objection, but there is good reason to believe this may not be true. Even if it were true, Jesus clearly appoints women to apostolic service and to preach.
Other traditions that sprang from this myopic male world view have already been set aside. For example, the stipulation that only males may stand in God's service or touch the Holy vessels (Pope Soter c. 176 and Pope Sixtus c. 120) and the prohibition against women from actively participating in liturgical activities (Pope Boniface c. 418). Members of the laity, both male and female, serve at the altar in Roman Catholic Churches, and all are called to participate actively in liturgical services. Women preach and teach Catholic theology and lead Catholic organizations and institutions around the world.
