In our diocese, in about a week, there will be ordinations of four deacons, and I thought I would elaborate a little on Ordinations, especially of Deacons. Ordination Liturgies are almost always held at a Diocesan level, with the Bishop presiding.
In the years prior to the Second Vatican Council, the only men ordained as deacons were seminarians who were completing the last year or so of graduate theological training, who received the order several months before ordination to the priesthood.
Following the recommendations of the council (in Lumen Gentium 29), in 1967 Pope Paul VI restored the Diaconate.
Lumen Gentium 29: At a lower level of the hierarchy are deacons, upon whom hands are imposed "not unto the priesthood, but unto a ministry of service."(74*) For strengthened by sacramental grace, in communion with the bishop and his group of priests they serve in the diaconate of the liturgy, of the word, and of charity to the people of God. It is the duty of the deacon, according as it shall have been assigned to him by competent authority, to administer baptism solemnly, to be custodian and dispenser of the Eucharist, to assist at and bless marriages in the name of the Church, to bring Viaticum to the dying, to read the Sacred Scripture to the faithful, to instruct and exhort the people, to preside over the worship and prayer of the faithful, to administer sacramentals, to officiate at funeral and burial services. Dedicated to duties of charity and of administration, let deacons be mindful of the admonition of Blessed Polycarp: "Be merciful, diligent, walking according to the truth of the Lord, who became the servant of all."(75*)

Since these duties, so very necessary to the life of the Church, can be fulfilled only with difficulty in many regions in accordance with the discipline of the Latin Church as it exists today, the diaconate can in the future be restored as a proper and permanent rank of the hierarchy. It pertains to the competent territorial bodies of bishops, of one kind or another, with the approval of the Supreme Pontiff, to decide whether and where it is opportune for such deacons to be established for the care of souls. With the consent of the Roman Pontiff, this diaconate can, in the future, be conferred upon men of more mature age, even upon those living in the married state. It may also be conferred upon suitable young men, for whom the law of celibacy must remain intact.

There is only one Order of Deacons, so the adjective "permanent" as in "Permanent Diaconate" is no longer used. Men preparing for the priesthood are ordained to the (transitional) diaconate, first.
Men studying for the Dioconate undergo a formation period of four to five years. This training resembles a collegiate course of study. They are instructed in philosophy, theology, Holy Scriptures, homiletics, sacramental studies, evangelization, ecclesiology, counseling, and pastoral care and ministry before ordination. Although they are assigned to work in a parish, deacons are directly responsible to the local Bishop who appoints them. Unlike most clerics, permanent deacons may also have a secular profession and do not receive a salary for their ministry.
The ministry of the deacon in the Catholic Church is described as one of service in three areas: the Word, the Liturgy and Charity. The deacon's ministry of the Word includes proclaiming the Gospel during the Mass, preaching and teaching. His liturgical ministry includes various parts of the Mass proper to the deacon, including being an ordinary minister of Holy Communion and the proper minister of the chalice when Holy Communion is administered under both kinds. The ministry of charity involves service to the poor and marginalized and working with parishioners to help them become more involved in such ministry. As clerics, they are required to recite the Liturgy of the Hours daily.
Deacons, like priests and bishops, are ordinary ministers of the sacrament of Baptism and can serve as the church's witness at the sacrament of Holy Matrimony, which the bride and groom administer to each other (though if the exchange of vows takes place in a wedding Mass, or Nuptial Mass, the Mass is celebrated by the priest and the deacon acts as another witness). Deacons may preside at funeral rites not involving a Mass (e.g., the final commendation at the gravesite or the reception of the body at a service in the funeral home), and may assist the priest at the Requiem Mass. They can preside over various services such as Exposition of the Blessed Sacrament, and they may give certain blessings. They cannot hear confession and give absolution, anoint the sick, or celebrate Mass.
At Mass, the deacon is the ordinary minister of the proclamation of the Gospel (in fact, a priest, bishop, or even the Pope should not proclaim the Gospel if a deacon is present) and of Holy Communion (primarily, of the Precious Blood). Deacons have the faculty to preach the homily by right of their ordination unless the priest presider retains that ministry to himself at any particular Mass.
The vestments most particularly associated with the Western Rite Catholic deacon are the alb, stole and dalmatic (image). Deacons, like priests and bishops, must wear their albs and stoles; deacons place the stole over their left shoulder and it hangs across to their right side, while priests and bishops wear it around their necks. The dalmatic, a vestment especially associated with the deacon, is worn during the celebration of the Mass and other liturgical functions; its use is more liberally applied than the corresponding vestment of the priest, the chasuble.
