II.
The Congregations of Believers being also appointed to sing the praises of God, and to comfort and fortifie themselves by the use of Psalms, All shall be advertis'd to carry their Psalm Books to Church, and those who by disdain shall neglect to have them, shall be sensur'd, as also those which shall not be uncover'd in the time of singing, as well before as after Ser∣mon, and also during the time of celebrating the Sacra∣ments.
Seeing Prayer and singing Psalms are things Essential to Piety, our Discipline doth justly prescribe the Manner and Means to do it as becometh, and to declare those worthy of sensure which shall transgress their Ordi∣nance.
It requires the same thing in the time of celebrating the Sacraments, and in desiring it, it nothing differs from the practice of the Antient Church, which had so great Respect for Baptism and the Lords Supper, that it suffer'd not the Catechumeny, Energumeny, or Penitents, to be present at celebration of one or the other, calling them both Terrible Misteries.
