Disputed Questions

Quaestiones Disputatae

Interactive maps of the great theological debates — each one lets you answer the questions for yourself and see exactly where you land, who else stands there, and where the reasoning holds or breaks.

The Studies
I · Grace & Providence
Ready
On Grace & Free Will
De Gratia et Libero Arbitrio
How do divine sovereignty, grace, and human freedom fit together? An ecumenical map spanning Reformed, Lutheran, Arminian, Orthodox, and Catholic answers — flagging the incoherent combinations and the modern departures from the historic consensus.

II · God & Suffering
Ready
On the Problem of Evil
De Malo
Why does a good and almighty God permit evil? An ecumenical map of the classic answers — Epicurus and Mackie, Augustine and Aquinas, Leibniz and Hick, Plantinga and Adams, Ivan Karamazov and the voice from the whirlwind — naming where you land, who else stands there, who rejects it and where, and whether the answer can bear the weight.

III · The Sacraments
Planned
On Infant Baptism
De Baptismo Parvulorum
Should the children of believers be baptized? A map from the covenant and household arguments to the credobaptist case — Reformed paedobaptism, Lutheran and Catholic regeneration, Baptist believer's baptism, and where each reads the same texts differently.
IV · Scripture
Ready
On the Canon of Scripture
De Canone Scripturae
Which books belong, and by what rule? State your principle, then sit as judge over each disputed book — the deuterocanon and the New Testament's own once-disputed books — reading its full history before you rule. The docket names the canon you reconstructed and tests whether your verdicts kept faith with your own stated rule.

V · Salvation
Planned
On Justification
De Iustificatione
Is justification a legal declaration or a real transformation? Imputed versus infused righteousness, faith and works, and the root of most of what divides the traditions.
VI · Salvation
Planned
On Assurance of Salvation
De Certitudine Salutis
Can one know with certainty that one is saved? Certainty of faith versus firm hope, eternal security versus the possibility of falling away, and the warning passages that press on every side.
VII · Salvation
Ready
On the Perseverance of the Saints
De Perseverantia Sanctorum
Can the truly saved be finally lost? An ecumenical map from Reformed perseverance and Free-Grace security to Lutheran, Arminian, Catholic, and Orthodox conditional grace — with Augustine's gift of perseverance and the rigorists. Rule on the hard verses yourself (1 John 2:19; John 10:28; Hebrews 6) and see whether your position can bear its own proof-texts.

VIII · The Church
Planned
On the Papal Office
De Primatu Romani Pontificis
What did the keys given to Peter establish? From Isaiah 22 and Matthew 16 through the early witnesses, the development of primacy, and the definition of 1870 — with the honest limits at each step.
