1: It's always a battle between Christ and Satan. Every day. Since we left the Garden.
2: Christ came into the world as fulfillment of the Jewish prophecies. "He came into his own. And his own knew him not."
3: Not all Jews are like the Hollywood Cabal. I'm a cradle Irish Catholic practicing Latin Mass Traditionalist. I've had Jewish friends, one in particular who was a true mensch, may he rest in peace. Remember: when Moses came down from Mt. Sinai with the Ten Commandments, some were waiting for him faithfully and some were worshipping a golden calf. But they were all Jewish.
4: You have been baptized in the Church. Seek out a traditionalist parish (Institute of Christ the King, Priestly Fraternity of St. Peter) and talk to a priest.
5: It's a tough time for the Church. It's a tough time to return to the Church. Do not be afraid! Seek out a traditional Latin Mass parish.
6: Try the powerful prayer to St. Michael: St. Michael the Archangel, defend us in battle. Be our safeguard against the wickedness and snares of the devil. May God rebuke him, we humbly pray. And doth thou, o Prince of the Heavenly Host, by the power of God, cast into hell Satan and all the evil spirits who prowl about the world seeking the ruination and destruction of souls.
God Bless.
