The Holy Bible is the primary canon of NCAY (NC&C 297) to which no other work may be added, and from which no existing books may be removed, until the dawning of the Millennial Day and the theocratic govermnment of Yah'shua the Messiah (Jesus Christ) is established upon the earth.

The secondary canon of NCAY, which is subordinate to the primary in all matters of doctrine and Christian practice, is (as of February 2012) as follows:

• 1. The Wisdom of Solomon and Ecclesiasticus, from the Apocrypha;

• 2. The Testaments of the Twelve Patriarchs and Joseph & Asenath from the Pseudepigrapha;

• 3. The Epistles of the Sub-Apostolic Fathers, consisting of:
  
  • 3.a. Clement to the Corinthians (1 Clement);

  • 3.c. Polycarp to the Philippians (Polycarp);
  • 3.d. Marcion, called the Martrydom of Polycarp (Martrydom);
