That which the apostles and primitive times did so much and so long pray for, tho' never long with much quietness enjoyed; that which our fathers in these latter times have fasted, prayed and mourned after, yet attained not; even the cause which many dear saints now with God, have furthered by extremest sufferings, poverty, imprisonment, banishment, death, even ever since the first dawning of reformation: that and the very same is the very cause and work that we are come now, through the mercy of Jesus Christ, not only to pray for, but swear to. And surely it can be no other, but the result and answer of such prayers and tears, of such sincerity and sufferings, that three kingdoms should be thus born, or rather new-born in a day; that these kingdoms should be wrought about to so great an engagement, than which nothing is higher. For this end kings reign, kingdoms stand, and states are upheld.
It is a special grace and favour of God unto you, brethren, (Reverend and Honourable) to vouchsafe you the opportunity, and to put into your hearts, as this day, to engage your lives and estates in matters so much concerning Him and His glory. And if you should do no more, but lay a foundation stone in this great work, and by so doing engage posterity after you to finish it, it were honour enough: but there may yet further use be made of you, who now are to take this oath. You are designed as chief master-builders, and choice instruments for the effecting of this settled peace and reformation; which, if the Lord shall please to finish in your hands, a greater happiness on earth, nor a greater means to augment your glory and crown in heaven, you are not capable of. And this, let me further add for your encouragement, of what extensive good, and fruit in the success of it, this very oath may prove to be, we know not. God hath set His covenant like the heavens, not only for duration, but like also for extension. The heavens move and roll about, and so communicate their light, and heat, and virtue, to all places and parts of the earth; so doth the covenant of God; so may this gift be given to other covenants, that are framed to this pattern. How much this solemn league and oath may provoke other reformed churches to a further reformation of themselves; what light and heat it may communicate abroad to other parts of the world, it is only in Him to define, to whom is given the utmost ends of the earth for His inheritance, and worketh by His exceeding great power great things out of small beginnings.
But however, this I am sure of, it is a way in all probability most likely to enable us to preserve and defend our religion against our common enemies; and possibly a more sure foundation this day will be laid for ruining popery and prelacy, the chief of them, than yet hath been led unto in any age. For popery hath been a religion ever dexterous in fencing and mounting itself by association and joint strength. All sorts of professors amongst them are cast into fraternities and brotherhoods; and these orders carefully united by vow one with another, and under some more general notion of common dependence. Such states also and kingdoms, as they have thus made theirs, they endeavour to improve and secure by strict combinations and leagues each to other; witness of late years that la sainte ligue, the holy league. It will not be unworthy your consideration, whether, seeing the preservation of popery hath been by leagues and covenant, God may not make a league or covenant to be the destruction of it. Nay, the very rise of popery seemeth to be after such a manner, by kings, that is kingdoms assenting and agreeing perhaps by some joint covenant (the text saith, "with one mind," why not then with one mouth) to give their power and strength unto the beast, and make war against the Lamb. For you read, "the Lamb shall overcome the beast," and possibly with the same weapons. He is the Lord of lords, and King of kings, He can unite kings and kingdoms, and give them one mind also to destroy the whore, and be her utter ruin. And may not this day's work be a happy beginning of such a blessed expedition?
Prelacy, another common enemy, that we covenant and swear against. What hath been, or what hath the strength of it been, but a subtile combination of clergymen, formed into a policy or body of their own invention, framing themselves into subordination and dependence one upon another; so that the interest of each is improved by all, and a great power by this means acquired to themselves, as by sad experience we have lately found. The joints and members of this body, you know, were knit together by the sacred engagement of an oath, the Oath of Canonical Obedience, as they called it. You remember also, with what cunning industry they endeavoured lately, to make this oath and covenant more sure for themselves and their posterity, and intended a more public, solemn and universal engagement; than since Popery, this cause of theirs, was ever maintained or supported by: and questionless, Ireland and Scotland also must at last have been brought into this holy league with England. But blessed be the Lord, and blessed be His good hand, the parliament that, from the indignation of their spirits against so horrid a yoke, have dashed out the very brains of this project, and are now this day present before the Lord, to take and give possession of this blessed ordinance, even an oath and covenant, as solemn, and of as large extent, as they intended theirs; uniting these three kingdoms into such a league and happy combination, as will doubtless preserve us and our reformation against them, though their iniquity, in the mysteries of it, should still be working amongst us. Come, therefore (I speak in the words of the prophet) "let us join ourselves to the Lord," and one to another, and each to all, "in a perpetual covenant that shall not be forgotten."
We are now entering upon a work of the greatest moment and concernment to us, and to our posterity after us, that ever was undertaken by any of us, or any of our forefathers before us, or neighbouring nations about us; if the Lord shall bless this our beginning, it will be a happy day, and we shall be a happy people. An oath is a duty of the first commandment, and therefore of the highest and noblest order and rank of duties, therefore must come forth attended with choicest graces, especially with these two, humility and fear.
Fear, not only of God, which ought to be in an eminent measure. Jacob sware by the fear of his father Isaac, as if he coveted to inherit his father's grace, as well as his father's God: but also, fear of an oath, it being a dreadful duty, and hath this peculiar, it is established by the oath of God, "I have sworn, that unto Me every tongue shall swear." It is made the very character of a saint, he fears an oath.
Humility is another grace requisite. Set your hearts before God in an humble obedient frame. "Thou shall fear the Lord thy God, and serve Him, and swear by His name." The apostle Paul was sensible of this engagement, even in the very act of this duty. "I call God to witness, whom I serve in my spirit:" although it be a work of the lips, yet the heart, and the whole man must be interested, if we expect this worship to be acceptable. "Accept the free-will offering of my mouth, and teach me Thy judgments."
Also it must be done in the greatest simplicity and plainness of spirit, in respect of those with whom we covenant; we call God as a witness betwixt us, who searcheth the heart: "With Him is wisdom and strength, the deceived and deceiver are His." He hath wisdom to discover, and strength to punish, if our hearts be not upright to our brethren in this matter. Let us be contented with this, that the words of our covenant be bands; it may not be, so much as in the desire of our hearts, that they should become snares, no not to the weakest and simplest person that joineth with us. On the whole work make your address unto God, as Jacob did to his father Isaac, and let there be the like fear and jealousy over your spirits. "My father peradventure will feel me, and I shall seem to Him as a deceiver, and I shall bring a curse upon me, and not a blessing."
I take liberty with more earnestness to press this care upon you, because I have observed oaths and covenants have been undertaken by us formerly, and by the command of authority, the fruit whereof, though great, yet answered not our expectation; the Lord surely hath been displeased with the slightness of our hearts in the work. I beseech you be more watchful, and stir up your hearts with more industry this day than ever before. As it is the last oath you are likely to take in this kind, so it is our last refuge, Tabula post naufragium. If this help us not, we are likely to remain to our dying day an unhappy people; but if otherwise, "You will indeed swear with all your hearts, and seek the Lord with your whole desire, God will be found, and give you rest round about."
And having sworn, and entered into this solemn engagement to God and man, make conscience to do accordingly; otherwise it is better thou shouldst not vow. As is said of fasting, "It is not the bowing down of the head for a day;" so of this solemn swearing, It is not the lifting up of the hand for a day, but an honest and faithful endeavouring after the contents of this covenant, all our days. A truce-breaker is reckoned up amongst the vilest of Christians, so a covenant-breaker is listed amongst the worst of heathens, but he that sweareth and changeth not, tho' he swear to his hurt, that is, he that will keep his covenant and oath, tho' the contents of it prove not for him, nay possibly against him, yet he will keep it for his oath's sake, such an one "shall have his habitation with the most High, and dwell in His tabernacle." And as for you, reverend brethren, that are ministers of the gospel, there is yet another obligation will lie upon you: let us look to ourselves, and make provision to walk answerable to this our covenant, for the gospel's sake: it will reflect a great aspersion upon the truth of the gospel, if we should be false or inconstant in any word or purpose, tho' in a matter of less consequence, as you can easily collect from that apology of Paul. How much more in such a case as this is, if we should be found to purpose, nay more, to vow, and covenant, and swear, and all this according unto the flesh, and with us there should be, notwithstanding all these obligations, yea, yea, and nay, nay.
