consequently that there is no other kind of assaults but meerly spiritual, and therefore the Word of God, the most proper _Medium_ with sound reason, to judge of the power of Spirits and Devils by. [Sidenote: _Gregor. sup. Ezekiel._ _Homil._ 6.] [Sidenote: 1 Tim. 1. 17.] [Sidenote: Heb. 12. 9.] 3. That the Scriptures and sound reason are the only true and proper _Medium_ to decide these Controversies by, is most undeniably apparent, because God is a Spirit, and the invisible God, and therefore best knows the nature and power of the spiritual and invisible World, and being the God of truth, can and doth inform us of their power and operations, better than the vain lyes and figments of the Heathen Poets, or the dreams of the Platonick School, either elder or later, nay better than all the notional and groundless speculations of the Schoolmen, of whom it may truly be said that, _Rivulo divinæ Scripturæ relicto, in abyssos vanarum opinionum incidêrunt_. Nay these can better inform us in this point, than the Writings of all Mortals besides, and therefore whatsoever may be said to the contrary, may receive its answer from the Father: _Quod de Scripturis sacris authoritatem non habet, eâdem facilitate contemnitur, quâ probatur_. Therefore he being _the King eternal, immortal, invisible, and the only wise God_, of none can we so truly and certainly learn these things, as of him who hath plentifully taught us in his Word all things necessary to Salvation, _that the man of God may be perfect, throughly furnished to every good work_. Nay _he is the Father of Spirits_, and therefore truly knoweth, and can and doth teach us their Natures, Offices, and Operations. [Sidenote: _Vid. Orig. sacr._ _l._ 1. _c._ 1. _p._ 15.] [Sidenote: Levit. 18. 22, 23, 24.]
