Protestant and Evangelical Christians, from the Reformers
onward, accept the shorter Old Testament canon, 39 books,
from the Hebrew Palestinian Canon. Jews have the same
canon as Protestants.
Canonical books are those books which have been
acknowledged as belonging to the list of books the Church
considers to be inspired and to contain a rule of faith and
morals.
Some criteria used to determine canonicity were
• special relation to God, i.e., inspiration;
• apostolic origin;
• used in Church services, i.e., used by the community
of believers guided by the Holy Spirit.
