Fletcher next undertakes to show and prove that God the Father has a proper Son, by whom He made the world; that our Lord Jesus Christ claimed the divine honour of being this Son; that He is the Redeemer and Saviour of lost mankind; that He is to be the final and universal Judge; and that divine worship was paid to Him by patriarchs, prophets, and Apostles, and is His undoubted right.

Fletcher’s second pamphlet, entitled “Socinianism Unscriptural,” consists of eight letters, addressed to Dr. Priestley, in which he shows that Socinians err when they assert that the prophets always spoke of the Messiah as of a mere man like themselves. He proves that our first parents expected a Divine Messiah, and that the Divine Person who appeared to the patriarchs, and to Moses, was Jehovah, the Son, or Christ in His pre-existent state; that the foundation of the proofs of Christ’s divinity, in the writings of the prophets, is laid in the three original prophecies (Gen. iii. 15, xxii. 16, etc., and xlix. 8–10), recorded by Moses concerning the Messiah; that all the prophets bear witness to His Godhead, as do also the Evangelists and Apostles.

This is a meagre outline of Fletcher’s exceedingly able pamphlet, but nothing more can be here attempted. Two brief extracts, however, may be added, illustrative of his style:—

“I have proved that the king of Israel who brought his people out of Egypt was Christ, in His pre-existent nature. Moses was the prime minister of this great King; Joshua, the general of His armies; the tabernacle, His palace; the mercy-seat, His throne; the ark, His royal standard; the priests, His officers; the Levites, His guards; and the shekinah, the visible display of His presence.”

“Read, dear Sir, the Scriptures without the veil of your system, and you will see that the Messiah, the wonderful Person whom you so constantly endeavour to degrade, was to be a mediating Prophet, like Moses; an atoning Priest, like Aaron; a pacific King, like Solomon; a royal Prophet, like David; a kingly Priest, like Melchisedec; the Everlasting Father, as the Logos by whom all things were created; and the Mighty God, as the proper Son of Him with whom He shares, in the unity of the Divine Spirit, the supreme title of ‘Jehovah, Lord of hosts.’”

It has been already shown in a letter which Fletcher addressed to Wesley in 1755, the year of his conversion, that he was what is commonly called a Millenarian. Twenty-nine years had elapsed since then. During this long interval, no man had been a more diligent and devout student of the Holy Scriptures than himself, and yet his Millenarian belief remained unchanged. Hence the following remarkable passage in his “Socinianism Unscriptural.” After quoting and paraphrasing Isa. lxvi. 15–24, Fletcher proceeds to say:—

“Here ends Isaiah’s account of that glorious reign of Jehovah-Shiloh, which the fathers called the ‘Millennium,’ as being to last a thousand years, and during which it is probable our Lord will use these extraordinary means to keep all the nations in the way of obedience:—1. A constant display of His goodness over all the earth, but particularly in and about Jerusalem, where the Lord will manifest His glory, and bless His happy subjects with new manifestations of His presence every Lord’s day and every new moon. 2. A distinguishing interposition of Providence which will withhold the Messiah’s wonted blessings from the disobedient (Zech. xiv. 17). 3. The constant endeavours of the saints, martyrs, patriarchs, prophets, and Apostles, raised from the dead and conversing with men, as Moses and Elijah did with our Lord’s disciples upon the mount, where they were indulged with a view of His glorified person, and of His ‘kingdom come with power.’ These glorified high priests and kings, as ministers and lieutenants of the Messiah, will rule all churches and states with unerring wisdom and unwarped fidelity. 4. The care that the Lord Himself will take to set apart for the ministry, under His glorified saints, those who in every nation shall distinguish themselves by their virtue and piety. This seems to be the meaning of His own words: ‘And when they shall come out of all nations to My holy mountain, I will take of them for priests and Levites, saith the Lord,’ Isaiah lxvi. 20, 21. 5. A standing display of the ministration of condemnation, as appears from Isaiah lxvi. 24, and from other parallel Scriptures. 6. At the same time that the ministration of condemnation will powerfully work upon the fears of mankind to keep men in the way of duty, an occasional display of the ministration of righteous mercy will work upon their hopes. How will those hopes be fired when they shall ‘see the Lamb’ of God ‘standing on the Mount Sion, and with Him’ His ‘hundred and forty-four thousand’ worthies, ‘having His Father’s name,’ Divine Majesty, Irresistible Power, Ineffable Love, and Bliss Inexpressible, ‘written on their foreheads!’ (Rev. xiv). But, 7. What will peculiarly tend to keep men from lapsing into rebellion against God will be the long life of the godly, and the untimely death of those who shall offer to tread the paths of iniquity. The godly shall attain to the years of antediluvian patriarchs, and the wicked shall not live out half their days; they shall not live above a hundred years; or, to speak after our manner, they shall die in their childhood. This seems to be Isaiah’s meaning in Isaiah lxv. 17–25.”

Leaving it to others to advocate or to attack these interpretations of Scripture, the present writer will only add, that thus full of firm unwavering faith in the Divine majesty and glorious kingship of his Lord and Saviour Jesus Christ, the devout and reverent Fletcher drew near to the mysterious spirit-world.

In harmony with all this, Fletcher wrote to his friend, Mr. Henry Brooke, of Dublin, as follows:—

“Madeley, April 27, 1784.
