§1. Each nation is to have a programme of priestly formation which is to be established by the conference of bishops, attentive to the norms issued by the supreme authority of the Church, and which is to be confirmed by the Holy See. This programme is to be adapted to new circumstances, also with the confirmation of the Holy See, and is to define the main principles of the instruction to be given in the seminary and general norms adapted to the pastoral needs of each region or province.
§2. All seminaries, both diocesan and interdiocesan, are to observe the norms of the program mentioned in §1.
