"I will raise up for them a prophet like you from among their fellow Israelites, and I will put my words in his mouth." (Deuteronomy 18:18)
The Levites and priests receive no land inheritance; the LORD is their inheritance. They live from the offerings of the people. Moses forbids every form of divination, sorcery, omens, witchcraft, and consulting the dead: these are detestable to the LORD and are the reason the nations are being dispossessed. Israel must be blameless before the LORD and not seek guidance from these sources. Then the great prophecy: I will raise up for them a prophet like you from among their fellow Israelites, and I will put my words in his mouth. He will tell them everything I command him. I myself will call to account anyone who does not listen to my words that the prophet speaks in my name.
The test of a true prophet: if what they say does not take place, it is not from the LORD. The Acts of the Apostles applies this prophecy directly to Jesus: Moses said the LORD your God will raise up for you a prophet like me from among your own people; you must listen to everything he tells you (Acts 3:22). The Catechism identifies the prophet like Moses as one of the clearest messianic prophecies in the Pentateuch, pointing to the one who speaks God's own words with the authority of the Son rather than merely the servant (CCC 64). Jesus is the prophet, the priest, and the king of Deuteronomy fulfilled in one person.
Brothers and sisters, do not seek guidance from diviners, sorcerers, or those who consult the dead. The counsel available from God through prayer, Scripture, and the wise guidance of the Church is superior to everything the occult can offer, and it comes without the defilement of consulting what God has declared detestable. Go to the prophet like Moses. He is still speaking.
Lord Jesus, the prophet like Moses whom the Father raised up, with his words in your mouth: we listen to everything you tell us. Speak your word into every situation where we are tempted to seek guidance from lesser sources. Through Christ our Lord. Amen.
