The Principles of Doctrine are:

It is not the Word that makes the Church, but the understanding of it [DSS 76]. The Church is according to its Doctrine and the Doctrine is out of the Word. However the Doctrine does not instaurate the Church, but the integrity and purity of the Doctrine, consequently the understanding (intellectus) of the Word.
[TCR 245; cf. TCR 243, TCR 244, NJHD 243]

The Doctrine is spiritual out of coelestial origin not out of rational origin.
[cf. A.C. 2496, 2497, 2510, 2516, 2533, 2859; A.E. 19]

The Third Testament without Doctrine is as a candlestick without light, and those who read that Testament without Doctrine, or who do not acquire for themselves Doctrine out of the Third Testament, are in darkness as to all Truth.
[cf. D.S.S. 50-61]

Teachings Out Of the Word of the Third Testament...

It is not the Word that makes the Church, but the understanding of it.
(Doctrine of the Sacred Scripture 76).

From the Latin of Third Testament: 

...non Verbum faciat ecclesiam, sed intellectus ejus...  (DSS 76))

The Church is according to its Doctrine and the Doctrine is out of the Word. However the Doctrine does not instaurate the Church, but the integrity and purity of the Doctrine, consequently the understanding (intellectus) of the Word  (TCR 245).

From the Latin of Third Testament: 

Quod ecclesia sit secundum doctrinam ejus, et quod doctrina sit ex Verbo, [notum est]; sed usque doctrina non instaurat ecclesiam, sed integritas et puritas doctrinae, consequenter intellectus Verbi; (TCR 245)
