Tiết 2. Những Điều Cần Thiết Để Lãnh Nhận Chức Thánh (Điều 1033-1039)

Only one who has received the sacrament of sacred confirmation may lawfully be promoted to orders.

§1 An aspirant to the diaconate or to the priesthood is not to be ordained unless he has first, through the liturgical rite of admission, secured enrolment as a candidate from the authority mentioned in cann. 1016 and 1019. He must previously have submitted a petition in his own hand and signed by him, which has been accepted in writing by the same authority.
§2 One who has by vows become a member of a clerical institute is not obliged to obtain this admission.

§1 Before anyone may be promoted to the diaconate, whether permanent or transitory, he must have received the ministries of lector and acolyte, and have exercised them for an appropriate time.
§2 Between the conferring of the ministry of acolyte and the diaconate there is to be an interval of at least six months.

For a candidate to be promoted to the order of diaconate or priesthood, he must submit to the proper Bishop or to the competent major Superior a declaration written in his own hand and signed by him, in which he attests that he will spontaneously and freely receive the sacred order and will devote himself permanently to the ecclesiastical ministry, asking at the same time that he be admitted to receive the order.

A candidate for the permanent diaconate who is not married and likewise a candidate for the priesthood, is not to be admitted to the order of diaconate unless he has, in the prescribed rite, publicly before God and the Church undertaken the obligation of celibacy, or unless he has taken perpetual vows in a religious institute. [A Decree of the Congregation for Divine Worship and the Discipline of the Sacraments, Ritus ordinationum, 29.VI.1989 (AAS 82 (1990), 826-827) states that even a religious having taken sacred vows must specifically assume the obligation of celibacy before ordination to the diaconate]

A deacon who refuses to be promoted to the priesthood may not be forbidden the exercise of the order he has received, unless he is constrained by a canonical impediment, or unless there is some other grave reason, to be estimated by the diocesan Bishop or the competent major Superior

All who are to be promoted to any order must make a retreat for at least five days, in a place and in the manner determined by the Ordinary. Before he proceeds to the ordination, the Bishop must have assured himself that the candidates have duly made the retreat.
