Are Christians supposed to be open minded to other religions?

you must first understand the catholic religion, it is one all their own. Constantine Mixed paganism/heathenism with Christianity, therefore it is easy and quite clear to see they have their own "religion", it's not "Christian" religion that adheres to God's Holy Living Word, ask any priest, or Theologian they will confirm this, and the cathecism as well as the catholic encyclopedia do not deny this either..their religion is man made for man, God does not support this religion because it does not have any Biblical Basis, so do not wonder why they do not act as a child of God, it is clear as to why....as a matter of more fact, they have caused the whole world/all nations to be drunk in her fornications, the Protestants inadvertently took with them MANY of the adopted pagan doctrines, traditions and rituals, i.e sun day over God's Holy Sabbath, the "immortal soul" doctrine which is the heart and soul of Heathenism amongst others....God Bless
