Thus far of the special kind or peculiar nature of this authority; now to the several parts or acts of this power which the description comprehends in these expressions, (in dispensing the word, seals, censures, and all other ordinances of Christ.) The evangelical ordinances which Christ has set up in his church are many; and all of them by divine right that Christ sets up. Take both the enumeration of ordinances and the divine right thereof severally, as followeth. Jesus Christ our Mediator hath instituted and appointed these ensuing administrations to be standing and perpetual ordinances in his church: which ordinances for method sake may be reduced into two heads, according to the distribution of the keys formerly laid down, (chap. III.,) viz., ordinances appertaining, 1st, To the key of order or of doctrine; 2d, To the key of jurisdiction or of discipline. 1. Ordinances appertaining to the key of order or doctrine, viz: 1. Public prayer and thanksgiving are divine ordinances: for 1st, Paul writing his first epistle to Timothy, "that he might know how to behave himself in the house of God," 1 Tim. iii. 14, 15, among other directions in that epistle, gives this for one, "I exhort therefore that first of all supplications, prayers, intercessions, and giving of thanks be made for all men," 1 Tim. ii. 1, 2, "for this is good and acceptable in the sight of God our Saviour," verse 3. 2.

Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned, say amen at thy giving of thanks, seeing he understandeth not what thou sayest? for thou verily givest thanks well, but the other is not edified." 1 Cor. xiv. 14-17. 3. Further, the apostles did account public prayer to be of more concern than serving of tables, and providing for the necessities of the poor, yea, to be a principal part of their ministerial office, and therefore resolve to addict and "give themselves to the ministry of the word and to prayer," Acts vi. 4; and this was the church's practice in the purest times, Acts i. 13, 14, whose pious action is for our imitation. 4. And Jesus Christ hath made gracious promises to public prayer, viz., of his presence with those who assemble in his name; and of audience of their prayers, Matt, xviii. 19, 20. Would Christ so crown public prayer were it not his own ordinance? 2. Singing of psalms is a divine ordinance, being,
