Why would you say that? Jesus Christ, Word and Sacrament, centers the worship of the Catholic Church. Catholics also believe in the Holy Trinity, God the Father, Christ the Son, and the Holy Spirit, the Paraclete.
Mormons don’t have these beliefs at all.
The Catholic Church’s doctrine is closer to Judaism than Christianity.
1. Salvation by works alone
2. God’s presence in ONE location (Eucharist vs Holy of Holies)
3. No salvation outside of the Church (no protestants vs. no gentiles)
4. The view that “God’s house” must be grandiose and expensive (like Solomon’s temple)
5. One individual to communicate with God (Pope vs. High Priest)
6. Neither believe that the sacrifice of Christ paid for our sins forever.
Aside from those similarities I could also point to the selling of indulgences during the Protestant Reformation. Your money in exchange for forgiveness. That’s the same thing the money changers were doing in the synagogues when Jesus overturned their tables and drove them out with a whip.
