Are apparitions of Mary true messages from God?

from the old testament

• A Marian apparition is a claimed supernatural appearance of Mary, the mother of Jesus, in which a person or group of people reports seeing, hearing, or receiving a message from her. Throughout history, some have claimed that Mary has appeared to call people to prayer, repentance, devotion, or other spiritual practices.
• The Bible never mentions Marian apparitions specifically, but it provides a comprehensive framework for evaluating all supernatural experiences and claimed revelations. Throughout the Old Testament, God revealed Himself directly through prophets, angels, dreams, visions, and His Word, not through deceased believers returning to deliver new messages (Numbers 12:6–8; Deuteronomy 18:15–22).
• God explicitly forbids consulting the dead or seeking spiritual guidance from them (Deuteronomy 18:10–12; Isaiah 8:19–20; Leviticus 19:31; Leviticus 20:6).
• Miracles alone never prove divine authority. Even if a prophet performed signs or miracles, the message must be rejected if it leads people away from God (Deuteronomy 13:1–5; Deuteronomy 18:20–22).
  
• God warned that supernatural signs can accompany deception (Exodus 7:11–12; Deuteronomy 13:1–3).

from the new testament

• Hebrews 1:1–2 teaches that while God spoke through the prophets in the past, He has now spoken definitively through His Son, Jesus Christ. Because Christ is God's fullest revelation, Christians should be cautious of claims that apparitions of Mary deliver new revelations or messages that are necessary for the church.
  
• All Scripture is inspired by God and fully equips believers for every good work (2 Timothy 3:16–17). God has also given us everything we need for life and godliness through Christ (2 Peter 1:3). If Scripture is sufficient, then apparitions of Mary cannot provide additional authoritative revelation that believers need for salvation or faithful living.
• Rather than accepting every spiritual claim, Christians are instructed to "test the spirits" to determine whether they are from God (1 John 4:1–3) and to examine everything carefully (1 Thessalonians 5:20–21). This means that every claimed apparition of Mary must be evaluated by whether its message agrees completely with Scripture.
• Miracles and supernatural experiences do not automatically prove that a message comes from God. Jesus warned that false christs and false prophets would perform great signs and wonders capable of deceiving many people if possible (Matthew 24:24; Mark 13:22). Therefore, even if an apparition of Mary is accompanied by reported miracles or unexplained phenomena, those signs alone do not prove it is from God.
• Satan is capable of disguising deception as something beautiful or holy. Paul warns that Satan disguises himself as an angel of light, and his servants may likewise appear righteous (2 Corinthians 11:13–15). Because of this, Christians should not assume that an apparition is from God simply because it appears radiant, peaceful, or claims to be Mary.
• Jesus Christ is the only mediator between God and humanity. First Timothy 2:5 teaches that there is one mediator between God and mankind: Jesus Christ, and Hebrews invites believers to approach God directly through Him (Hebrews 4:14–16; 7:25). Any apparition of Mary that encourages believers to rely on Mary as a mediator or necessary channel to God would conflict with the New Testament's teaching about Christ's unique role.
• In the Bible, Mary herself consistently pointed people to Jesus rather than to herself. Her most famous recorded instruction is, "Do whatever He tells you" (John 2:5), and in Luke 1:46–55, she magnified the Lord rather than seeking honor for herself. Therefore, any genuine message associated with Mary would be expected to direct people exclusively to Christ rather than increasing devotion to Mary.
• The Bible never instructs believers to seek or expect messages from deceased saints. Instead, Christians are taught to seek God through Christ, rely on the Holy Spirit, devote themselves to Scripture, and remain grounded in the apostles' teaching (John 16:13–15; Acts 17:11; Ephesians 2:20). Since the New Testament gives no expectation that Mary or other deceased believers will appear with messages, claims of Marian apparitions should be approached with biblical discernment.

implications for today

We are to be cautious about claims of Marian apparitions. While not every person reporting an apparition is intentionally deceptive, Satan masquerades as an angel of light. We must be holding on to God's Word as authoritative, not to miraculous experiences.

The issue isn't whether God is capable of doing something supernatural—He certainly is. The question is whether He has instructed His people to seek or trust messages from apparitions. The New Testament repeatedly directs believers to Christ as God's final revelation, to Scripture as sufficient, and to Jesus as the only mediator between God and humanity. Rather than debating individual apparitions, invite the discussion to center on what God's Word clearly teaches.

When talking to someone who wants to discuss apparitions of Mary, remember that your goal is not to win an argument but to help someone treasure Christ more deeply. Many Catholics who believe in Marian apparitions sincerely love Jesus, so they should be approached with grace, patience, and respect rather than with suspicion or hostility. Let your confidence rest in the sufficiency of Scripture and the finished work of Christ, not in clever arguments. Keep bringing the conversation back to this question: Does this claimed apparition point people to trust in Christ alone and remain fully consistent with Scripture, or does it encourage confidence in something God has not revealed?
