Let me suggest a few points from that document that would aid modern churches:
The publick worship being begun, the people are wholly to attend upon it, forbearing to read any thing, except what the minister is then reading or citing; and abstaining much more from all private whisperings, conferences, salutations, or doing reverence to any person present, or coming in; as also from all gazing, sleeping, and other indecent behaviour, which may disturb the minister or people, or hinder themselves or others in the service of God.
AFTER reading of the word, (and singing of the psalm,) the minister who is to preach, is to endeavour to get his own and his hearers hearts to be rightly affected with their sins, that they, may all mourn in sense thereof before the Lord, and hunger and thirst after the grace of God in Jesus Christ, by proceeding to a more full confession of sin, with shame and holy confusion of face, and to call upon the Lord to this effect...
The section on the sermon I will post separately tomorrow, since it could be a mini-course in homiletics.
Times of sickness and affliction are special opportunities put into his hand by God to minister a word in season to weary souls: because then the consciences of men are or should be more awakened to bethink themselves of their spiritual estate for eternity; and Satan also takes advantage then to load them more with sore and heavy temptations: therefore the minister, being sent for, and repairing to the sick, is to apply himself, with all tenderness and love, to administer some spiritual good to his soul, to this effect.
He may, from the consideration of the present sickness, instruct him out of scripture, that diseases come not by chance, or by distempers of body only, but by the wise and orderly guidance of the good hand of God to every particular person smitten by them. And that, whether it be laid upon him out of displeasure for sin, for his correction and amendment, or for trial and exercise of his graces, or for other special and excellent ends, all his sufferings shall turn to his profit, and work together for his good, if he sincerely labour to make a sanctified use of God's visitation, neither despising his chastening, nor waxing weary of his correction.
