Post Show #42 - Red Flags of Bad Theology
A quick guide for Catholics of any experience level to see the signs of bad theology
During the episode I mentioned that ordinary Catholics can often recognize bad theology just by watching for certain patterns and clues. You don’t need a theology degree to notice when something is off.
I wasn’t able to get to my whole list, and I promised to make it available in a post show post—so here ya go!
Practical red flags
1. Treating the Magisterium as optional
If a Catholic teacher implies that individual Catholics get to decide which teachings of the Church they accept, that’s a warning sign.
Catholic theology begins with the premise that Christ entrusted authoritative teaching to the Church. Serious theological discussion can explain or explore teachings, but it does not place private judgment above the Magisterium.
When someone says, “Rome is wrong here and faithful Catholics must resist,” they’ve crossed that line.
2. Diminishing the authority of an Ecumenical Council
Another red flag is when a source tries to downgrade the authority or legitimacy of an ecumenical council.
For example, when people attempt to dismiss or minimize the authority of the Second Vatican Council, they are attacking something that belongs to the Church’s authentic teaching office.
Catholics can debate interpretations or applications of a council.
They cannot treat a council itself as optional or illegitimate.
3. Using older sources against the living Church
Another common tactic is quoting older documents, saints, or councils against the present Magisterium, as if the Church today has contradicted the past.
But Catholic theology works the other way around.
Sacred Tradition is authentically interpreted by the living Magisterium, not by individuals selecting historical texts and setting them against the Church’s current teaching authority.
4. Relying on conspiracy narratives
Be cautious when a theological source constantly frames things in terms of secret takeovers, infiltration, or hidden agendas inside the Church.
Claims that:
the Church has been “taken over”
popes are secretly undermining the faith
bishops are intentionally destroying Catholicism
may be emotionally compelling, but they undermine the Catholic doctrine that the Church will not defect from the faith.
5. Replacing the Church with a personality
If a source effectively teaches:
“Trust this priest / influencer / movement instead of Rome.”
…that’s another clear warning sign.
Catholic theology is ecclesial. It belongs to the life and authority of the Church, not to any single personality or movement.
6. Claiming to be the “faithful remnant”
A frequent pattern in unhealthy movements is the claim that:
“The real Church is only preserved by our group.”
When someone insists that nearly the entire Church has fallen away and only a small faction remains faithful, they are describing something much closer to sectarianism than Catholicism.
7. Confusing discipline with doctrine
Another mistake is treating changes in discipline as if they were changes in doctrine.
Catholic theology distinguishes between:
• Doctrine or dogma — truths of the faith that do not change
• Discipline or pastoral practice — things the Church can regulate or modify
When someone constantly blurs this distinction, they often claim the Church has “changed doctrine” when she has not.
8. Teaching Catholics to ignore the Catechism
If someone dismisses or undermines the authority of the Catechism of the Catholic Church, that should immediately raise questions.
The Catechism is the Church’s normative summary of the faith today. Not every sentence is an infallible definition, but it is a reliable expression of the Church’s teaching.
A Catholic source that encourages people to ignore it is already pointing them away from the Church.
A simple rule of thumb
If a source consistently pushes Catholics toward:
distrust of the pope
suspicion of councils or the magisterium
rejection of the Catechism (whole, or in part)
the belief that “the real Church exists somewhere else”
…it’s very likely not a healthy source of Catholic theology.
Authentic Catholic theology operates inside the life of the Church, not in opposition to it.
