Show me the verse where Christ said to respect other people's opinions on spiritual matters.

I'll wait.

John 14:16

Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.

And to all those "Christians" claiming we are not to judge? I'll leave you with this.

John 7:24 Judge not according to the appearance, but judge righteous judgment.

And to those "Christians" claiming Christ came to spread peace, love, and tolerance? I'll leave you with this.

Matthew 10:34-36

Think not that I am come to send peace on earth: I came not to send peace, but a sword.

35 For I am come to set a man at variance against his

father, and the daughter against her mother, and the daughter in law against her mother in law.

36 And a man's foes shall be they of his own household.
