You say that the only way to be saved is through faith in Christ. Isn't it narrow minded to think that there is only one way?
Then the Bible is narrow minded. Jesus said that no one could come to God, the Father, except through Him (John 14:6). Peter said that no one could be saved in any other way than through Christ (Acts 4:12). And Paul wrote that there is no other foundation except Jesus Christ (1 Corinthians 3:11). Faith in Christ is the only way of salvation.
