It's no different than a ouija or a seance.
It's your personal opinion even not based on actual knowledge about the issue and how the Church perceived it.
Not my opinion. Last time I checked, Holy Tradition and Holy Scripture supported one another, not contradicted.
Look closely, you will see divination partnered with the other magics. And if this is not enough, let me know, there is ton of other references throughout the Scriptures.
“Do not turn to mediums or necromancers; do not seek them out, and so make yourselves unclean by them: I am the Lord your God.
1 John 4:1
Beloved, do not believe every spirit, but test the spirits to see whether they are from God, for many false prophets have gone out into the world.
And a number of those who had practiced magic arts brought their books together and burned them in the sight of all. And they counted the value of them and found it came to fifty thousand pieces of silver.
See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits of the world, and not according to Christ.
And when they say to you, “Inquire of the mediums and the necromancers who chirp and mutter,” should not a people inquire of their God? Should they inquire of the dead on behalf of the living?
2 Kings 21:6
And he burned his son as an offering and used fortune-telling and omens and dealt with mediums and with necromancers. He did much evil in the sight of the Lord, provoking him to anger.
Idolatry, sorcery, enmity, strife, jealousy, fits of anger, rivalries, dissensions, divisions,
There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the Lord. And because of these abominations the Lord your God is driving them out before you.
But there was a man named Simon, who had previously practiced magic in the city and amazed the people of Samaria, saying that he himself was somebody great. They all paid attention to him, from the least to the greatest, saying, “This man is the power of God that is called Great.” And they paid attention to him because for a long time he had amazed them with his magic. But when they believed Philip as he preached good news about the kingdom of God and the name of Jesus Christ, they were baptized, both men and women. Even Simon himself believed, and after being baptized he continued with Philip. And seeing signs and great miracles performed, he was amazed.
And say, Thus says the Lord God: Woe to the women who sew magic bands upon all wrists, and make veils for the heads of persons of every stature, in the hunt for souls! Will you hunt down souls belonging to my people and keep your own souls alive?
Stand fast in your enchantments and your many sorceries, with which you have labored from your youth; perhaps you may be able to succeed; perhaps you may inspire terror. You are wearied with your many counsels; let them stand forth and save you, those who divide the heavens, who gaze at the stars, who at the new moons make known what shall come upon you. Behold, they are like stubble; the fire consumes them; they cannot deliver themselves from the power of the flame. No coal for warming oneself is this, no fire to sit before!
And the spirit of the Egyptians within them will be emptied out, and I will confound their counsel; and they will inquire of the idols and the sorcerers, and the mediums and the necromancers;

There shall not be found among you anyone who burns his son or his daughter as an offering, anyone who practices divination or tells fortunes or interprets omens, or a sorcerer or a charmer or a medium or a necromancer or one who inquires of the dead, for whoever does these things is an abomination to the Lord.
