Canon 348

1. For those who are destined for the priesthood, the studies

of the major seminary, without prejudice to can. 345, are to be

comprised of philosophical and theological courses, which can be

followed either successively or conjointly. These same studies

are to encompass at least six complete years in such a way that

two full years are devoted to the philosophical disciplines and

four full years to theological studies. 2. They ought to start

the philosophical-theological course with an introduction into

the mystery of Christ and the economy of salvation, and they

shall not finish until there has been shown, taking into consideration the order or hierarchy of the truths of Catholic doctrine,

the relationship between all the disciplines and their coherent

arrangement.
