Why does Christianity claim to be superior to all other faiths?
The supremacy of Christianity over all other faiths is not based on arrogance. It is simply based on facts. If your house were to catch on fire, what do you think would be superior at extinguishing the flames--water or gasoline? They are both liquids, but one is obviously better qualified at the task of quenching the fire.
God has plainly said that Christianity is superior to all other faiths. There is no coming together for the sake of love and understanding. Many liberal churches try to use the fight against racial hatred as an excuse for forming alliances with other faiths. The Christians who resist the unity movement are called intolerant.
The only intolerance we need to worry about is God's abhorrence of sin. If people reject Jesus Christ's gift of salvation, they will simply end up eternally lost.
"Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me" (John 14:6).
"Enter ye in at the strait gate: for wide is the gate, and broad is the way, that leadeth to destruction, and many there be which go in thereat: Because strait is the gate, and narrow is the way, which leadeth unto life, and few there be that find it" (Mat. 7:13-14).
