Mary & the Saints · Beginner
Asking the Saints to Pray for Us
“Why pray to dead people? The Bible says there is one mediator between God and man, Christ Jesus. Asking saints to intercede is unbiblical and takes glory away from Jesus.”
Practice drillsMary & the Saints · Beginner
Honoring Mary Without Worshiping Her
“Catholics treat Mary almost like a fourth person of the Trinity — statues, rosaries, titles like 'Queen of Heaven.' Isn't this Mariolatry that competes with worship due to God alone?”
Practice drillsSacraments · Beginner
Why Sacraments? Grace Through Matter
“Salvation is a matter of faith in the heart, not rituals with water, oil, and bread. Sacraments seem like empty man-made ceremonies that add nothing Scripture requires.”
Practice drillsWorship & Images · Beginner
Statues, Images, and the First Commandment
“'You shall not make for yourself a graven image... you shall not bow down to them or serve them' (Exodus 20:4-5). Catholic churches are full of statues that people kneel before — this is plain idolatry.”
Practice drillsScripture & Tradition · Intermediate
Scripture and Tradition vs. Sola Scriptura
“The Bible alone is the sole infallible rule of faith; all doctrine must be provable from Scripture alone, as 2 Timothy 3:16-17 says Scripture makes the man of God 'complete, equipped for every good work.' Tradition and a teaching Church only add human error.”
Practice drillsPapacy & Church · Intermediate
Peter's Primacy and the Papacy
“Jesus is the only foundation and head of the Church (1 Corinthians 3:11); Peter was just one apostle among equals, often getting things wrong (Galatians 2:11). The idea of one bishop having supreme authority over the whole Church was a later Roman power-grab, not something Jesus instituted.”
Practice drillsSacraments · Intermediate
The Eucharist and the Real Presence
“'This is my body' was obviously figurative, like Jesus saying 'I am the door' or 'I am the vine.' The Lord's Supper is a memorial meal, a symbolic remembrance, not literally the body and blood of Christ — that sounds cannibalistic.”
Practice drillsSacraments · Intermediate
Confession to a Priest
“Why confess sins to a fallible priest? 1 John 1:9 says if we confess our sins to God, he is faithful to forgive us. Only God can forgive sins (Mark 2:7); adding a human intermediary is unnecessary and unbiblical.”
Practice drillsGod & Reason · Advanced
The Existence of God and the Problem of Evil
“If God is all-powerful and all-good, why does he allow immense suffering — children dying of cancer, genocides, natural disasters? Either God cannot stop evil (not all-powerful) or will not (not all-good), so the God of classical theism does not exist.”
Practice drillsApologetics & History · Advanced
The Resurrection and New Testament Reliability
“The Gospels were written decades after Jesus by biased believers, copied and altered over centuries before printing existed. The resurrection story is a legend that grew over time, like other ancient miracle tales, not sober history.”
Practice drillsChurch History & Doctrine · Advanced
Development of Doctrine and the Ecumenical Councils
“Doctrines like the Trinity's technical vocabulary, the Immaculate Conception, or papal infallibility appear nowhere explicitly in the earliest Christian writings and were formally defined centuries later. Doesn't this prove the Church simply invented new doctrines over time rather than preserving what Jesus taught?”
Practice drillsSalvation · Advanced
Justification: Faith and Works
“'For by grace you have been saved through faith... not because of works' (Ephesians 2:8-9). Catholic teaching that good works and the sacraments contribute to salvation undermines the gospel of grace and reintroduces the very works-righteousness Paul condemned.”
