Ye have asked concerning the wisdom of referring certain important laws to the House of Justice. Before all else, this divine cycle is purely heavenly and spiritual, and concerned with the matters of the soul. It hath but little connection to physical, temporal, or worldly matters. The Christian dispensation was in like manner solely spiritual. Thus, in the entire New Testament, there appeareth naught but the prohibition of divorce and the allusion to the abrogation of the Sabbath. Even as He saith, 'the Son of man came not to judge the world but to save the world'. This most great cycle is likewise of purely spiritual character and is the bestower of life eternal. For the head cornerstone of the religion of God consisteth in refining the characters, reforming the manners, and improving the attributes of men. The purpose is that beings that are veiled may see, and that dark and defective realities may become illumined. 

All other ordinances are subservient to faith, certitude, confidence, and understanding. This blessed cycle being however the greatest of all divine cycles, it embraceth all spiritual and temporal matters, and is endowed with the utmost power and sovereignty. Therefore, those matters of major importance which constitute the foundation of the Law of God are explicitly recorded in the Text, but subsidiary laws are left to the House of Justice. The wisdom of this is that the times never remain the same, for change is a necessary quality and an essential attribute of this world, and of time and place. Therefore the House of Justice will take action accordingly.
