3. This is the profoundest mystery in Divinity, or rather the main foundation of all Evangelicall mysteries treated off by our Apostle unto the end of this Epistle. But this profound mystery it selfe hath the same hap which other deepe foundations have, that is, to be least seen or sought into by such as are otherwise exact surveyors of superstructures or buil∣dings raised above ground.
The summe of my present search or survey after this great mistery is this; How the everlasting Priest∣hood of the Sonne of God, and his consecration to it were prefigured, foreshadowed, or foretold either in the law or before the law!
Of the eternity of this our high Priests person, (that is the person of the Sonne of God) Melchi∣zedech long before the law, was the most illustrious type or picture. So was his order, or Sacerdotall fun∣ction, the most exact shadow of the Sonne of Gods everlasting Priesthood.
Of the qualification of the Sonne of God for this everlasting Priesthood, and of the manner of his Consecration to it, Aaron and other legall Priests his lawfull Successors, and the legall rites or man∣ner of their Consecration, were the most lively pi∣ctures.
First of the parallel betweene Aaron and his Suc∣cessors lawfully ordained, and the high Priest of our soules, for their qualifications required by the Law of God, and by the Law of nature.
Secondly of the parallel betweene Melchisedech and the Sonne of God, aswell for their persons, as for sacerdotall functions or exercises of them.
