This old notion that Jews and Christians are enemies is from Satan. Christians have had The Holy Spirit reveal the Truth, that Jesus is who He said He was, and is the only mediator between God and man. Jews are our brothers and we are to steadfastly pray for them, pray for Jerusalem, and protect them from harm.
No one is required to believe that, but no one is required to be in paradise with God. If you confess you are a Christian, you are taking on the chosen people as your family. We didn't make that choice, God did. Jews have been chosen by God to reveal His Son to the world, even if they are in rebellion to Him.
Whenever you hear the old question, "Did the Jews kill Christ, or the Romans?", just know that is straight from Satan because Jesus Himself said "no one takes His life, He gives it willingly."
If a Catholic cannot pray like a Jew, who are they praying to? Muslims pray to someone. Their god requires them to kill and doesn't guarantee them paradise unless they do. Their god judges them on works rather than Grace. Their god doesn't recognize Jesus as the Son Of God.
You can pray to a stick, or a rock carving, or anything else, but there is One True God, that is God. There is but one Mediator, and that is Jesus. Praying to a thing, a statue, or a dead person is blasphemy in the eyes of God.
Did you even read what I wrote? Where did you stop?
