Was the doctrine of the Trinity invented at the Council of Nicaea, or was it defined against a heretical novelty (Arianism)?

Was the Council of Nicaea (325) considered universally binding independent of Roman confirmation, or did its authority depend on papal ratification?

Did the early Church use Scripture alone as its rule of faith, without appeal to Tradition or an authoritative teaching office?

Eschatology

Did Augustine of Hippo — the most influential theologian of the Western Church — teach the existence of a state of post-mortem purification corresponding to the Catholic doctrine of Purgatory?

Does the Passion of Perpetua — one of the earliest precisely datable Christian documents — contain evidence of belief in a state of post-mortem purification from which souls can be released by prayer?

Did the early Church understand the Church as a visible, hierarchical institution with defined membership essential for salvation — or did it understand the Church primarily as an invisible fellowship of true believers?

The Sacraments

Did the early Church teach baptismal regeneration — that baptism actually forgives sins and regenerates the soul — or did it understand baptism as a symbol of inner conversion already accomplished?

The Sacraments

Did the early Church require sinners to confess to a bishop or priest and receive absolution, or did it teach that sins are forgiven by direct personal confession to God alone?

Scripture & Tradition

Did Irenaeus of Lyon use the publicly known succession of bishops in Rome as the criterion of orthodox teaching — implying that succession, not Scripture alone, is the rule of faith?

Was the title Theotokos — God-bearer, Mother of God — used by orthodox Christians before the Council of Ephesus defined it, or was it a theological innovation imposed by the council?
