I've not seen one clip from any heresy hunter out there who has actually given a good salvation message personally.
Well I think the Very Rev. Fr. Andrew Stephen Damick, an Archpriest in the Antiochian Orthodox Church and pastor emeritus of St. Paul’s Antiochian Orthodox Church in Emmaus, Pennsylvania, Dr. James Kennedy of blessed memory (reposed 2007) the late pastor of Coral Ridge, and Pope Emeritus Benedict XVI, who all are known for heresiology, or “heresy-hunting” as you call it, certainly meet your criteria. Importantly, of those three I would suspect only Dr. Kennedy was a cessationist per se, and his heresiology was entirely directed against non-Nicene churches such as Jehovah’s Witnesses, Christian Science, Mormonism, Unitarianism, and so on.
For that matter, if we go back to the early church, St. Irenaeus the bishop of Milan, who wrote
Against Heresies, St. Epiphanius the bishop of Salamis, who wrote the
Panarion (“Medicine chest” or “First-aid kit”) an expanded follow-on to address Arianism, Manichaeanism and other new heresies which popped up between the repose of St. Irenaeus in the second century and the late fourth century, when Epiphanius became bishop, and then in the eighth century, St. John of Damascus, who in turn combined the epitomes written about specific heresies by St. Epiphanius with profiles of new heresies to emerge in the previous 400 years, such as Nestorianism, Monothelitism, Islam, etc, into his Fount of Knowledge, which was a broad ranging work. Like St. Irenaeus and St. Epiphanius, who concluded their catalogues of ancient heresies (which always explained why the beliefs of groups like the Alogi or the Marcionites or the Eunomians were heretical) with a section discussing the true faith, St. John of Damascus did this as well, however, he is better remembered for that work,
An Exact Exposition of The Orthodox Faith, which I personally prefer to subsequent formidable works of systematic theology such as the
Summa Theologica of Aquinas, the
Institutes of Calvin and the
Kirchlich Dogmatik of Karl Barth, although perhaps my preference is for, as a genre, more compact works which are arguably dogmatic theology but not systematic theology. For instance,
Orthodox Dogmatic Theology by Protopresbyter Michael Pomazansky,
The Orthodox Church and
The Orthodox Way by Metropolitan Kallistos Ware, and
Mere Christianity by CS Lewis, which is interesting in that it represents the finest specimen of an ecumenical and catechetical work of dogmatic theology.
