The Blessed Virgin Mary

- →She remained a virgin before, during, and after Christ's birth
- →She was assumed body and soul into heaven
- →She intercedes for us as our spiritual mother
- →We honor her but do not worship her — worship belongs to God alone

Salvation

Key Points
- →Salvation is a free gift from God

- →Living faith produces good works
- →We can lose salvation through mortal sin
- →Final perseverance is also a gift of grace

The Last Things
Death, Judgment, Heaven, Hell, and PurgatoryAt death, each soul faces particular judgment. The destiny is heaven (often through purgatory) or hell. At the end of time, Christ will return and judge all humanity.
Key Points
- →Heaven: eternal life with God in perfect happiness
- →Hell: eternal separation from God, chosen by rejecting Him
- →Purgatory: purification for those who die in grace but imperfectly
- →The resurrection of the body at the end of time
- →The final judgment and the renewal of all creation
Scripture
Hebrews 9:27
What Catholics Don't Believe
Common misunderstandings about Catholic teaching
Myth: “Catholics worship Mary and the saints”
Truth: We honor (venerate) Mary and the saints, but we worship God alone. We ask them to pray for us, just as we ask friends on earth to pray for us.
Myth: “Catholics believe they earn salvation through works”
Truth: Salvation is a free gift of grace. Works are the fruit of saving faith, not a way to earn heaven. We cooperate with grace but can never merit it initially.
Myth: “Catholics added books to the Bible”
Truth: The Catholic Church determined the canon of Scripture in the 4th century. Protestant reformers removed books that had been in the Bible for over a millennium.
Myth: “Catholics confess to priests instead of God”
Truth: We confess to God through the priest, whom Christ authorized to forgive sins in His name (John 20:23). The priest acts in persona Christi.
Myth: “Catholics re-sacrifice Jesus at every Mass”
Truth: The Mass makes present the one sacrifice of Christ on Calvary. It is not a new sacrifice but a participation in the eternal sacrifice of Christ.
