The subject selected by John Rogers for his discourse on this occasion is one particularly relating to Rogerene dissent; it is the necessity of a new birth and the wonderful changes wrought in body and soul by that divine miracle.[73] That only by such an operation of the Holy Spirit can a man become in truth one with Christ, is the burden of the theme. Not only has the speaker wealth of scriptural foundation for this discourse, but by his own conversion, so sudden and so powerful, he has internal evidence of the mysterious change set forth in the New Testament. No subject could better bring out the fervor and eloquence of the man. He declares that the body of an unregenerate person is a body of Satan, Satan having his abode therein, and that the body of a regenerate person is a body of Christ, Christ dwelling in such a body. (See account of his son, Part I, Chapter II.) ----- Footnote 73: Apparently the Scripture expounded on this occasion was Romans viii. ----- It is (and is to be) a conspicuous feature of Mr. Saltonstall’s ministry that no experience of this kind is to be considered necessary to church membership; such a test as this would never allow of that great ingathering to the state church which he desires to see firmly established and maintained. The Rev. Gurdon Saltonstall and his accomplices do not listen to this discourse in concealment from the speaker, however they may stand apart from the hearers that gather cordially about the remarkable man in their midst. That these three men are his enemies, none know better than the keen-eyed man who beholds them there; but it may well be judged that their presence gives no tremor to his heart or his voice, but, the rather, adds nerve and emphasis. Mr. Saltonstall, watching his opportunity, and holding the attention of his accomplices, inquires of the speaker: “Will you say that your body is the body of Christ?” The reply of John Rogers shows the quick wit of the man. He evidently perceives the intention to entrap him, and is, moreover, unwilling to allow the expression, which he has been using in a general way, to bear this bald, personal application, with its intended insinuation of irreverence. “Yes, I do affirm that this human body (bringing his hand against his breast) is Christ’s body; for Christ has purchased it with His precious blood, and I am not my own, for I am bought with a price.” (See account of his son, Part I, Chapter II.) Even thus ingeniously and reverently the speaker adheres to his affirmation that the body of a man as well as his soul belongs after regeneration to Christ and is animated by Him.
