Let all the faithful, whether men or women, when early in the morning they rise from their sleep and before they undertake any tasks, wash their hands and pray to God; and so they may go to their duties. But if a any instruction in God’s word is held [that day], everyone ought to attend it willingly, recollecting that he will hear God speaking through the instructor and that prayer in the church enables him to avoid the day’s evil; any godly man ought to count it a great loss if he does
not attend the place of instruction, especially if he can read.
If a [specially gifted] teacher should come, let none of you delay to attend the place where the instruction is given, for grace will be given to the speaker to utter things profitable to all, and thou wilt hear new things, and thou wilt be profited by what the Holy Spirit will give thee through the instructor; so thy faith will be strengthened by what thou hearest, and in that place thou wilt learn thy duties at home; therefore let everyone be zealous to go to the church, the place where the Holy Spirit abounds.
But if on any day there is no instruction, let everyone at home take the Bible and read sufficiently
in passages that he finds profitable.
