Women priests and deacons
Why can a woman not be ordained?
"Only a baptized man (vir) validly receives sacred ordination." CIC, can. 1024. The Lord Jesus chose men (viri) to form the college of the twelve apostles, and the apostles did the same when they chose collaborators to succeed them in their ministry. Cf. Mk 3:14-19; Lk 6:12-16; 1 Tim 3:1-13; 2 Tim 1:6; Titus 1:5-9; St. Clement of Rome, Ad Cor. 42, 4; 44, 3: PG — Patrologia Graeca (Migne); 300. The college of bishops, with whom the priests are united in the priesthood, makes the college of the twelve an ever-present and ever-active reality until Christ's return. The Church recognizes herself to be bound by this choice made by the Lord himself. For this reason, the ordination of women is not possible. Cf. John Paul II, MD 26-27; CDF — Congregation for the Doctrine of the Faith, declaration, Inter insigniores: AAS — Acta Apostolicae Sedis (official gazette of the Holy See)Volume 69 (1977) at vatican.va — scanned PDF (1977) 98-116.
No one has a right to receive the sacrament of Holy Orders. Indeed, no one claims this office for himself; he is called to it by God. Cf. Heb 5:4. Anyone who thinks he recognizes the signs of God's call to the ordained ministry must humbly submit his desire to the authority of the Church, who has the responsibility and right to call someone to receive orders. Like every grace, this sacrament can be received only as an unmerited gift.
§1. The orders are the episcopate, the presbyterate, and the diaconate.
§2. They are conferred by the imposition of hands and the consecratory prayer which the liturgical books prescribe for the individual grades.
§3. Those who are constituted in the order of the episcopate or the presbyterate receive the mission and capacity to act in the person of Christ the Head, whereas deacons are empowered to serve the People of God in the ministries of the liturgy, the word and charity
A baptized male alone receives sacred ordination validly.
