Ask yourself, "Am I 'Savage' towards others?"
Interdenominational differences often cause people to raise aggressive defense against each other. This is not intended to happen if we truly lived the Gospel as taught by Jesus Christ.
Jesus Christ set up His church when He was on the Earth. Jesus Christ is Perfect, therefore anything He does or establishes must needs be perfect. Futhermore, if there are any changes made to that church which He established it would become imperfect, because you simply can't make something 'more than perfect'.
If Christ's Church had the offices of Prophet (Adam, Noah, Moses), Apostles (Peter, James, John), Seventy (Luke 10:1,17), Pastor/Bishop (1 Timothy 3:1), Teachers (1 Corinthians 12:28), Deacons (1 Timothy 3:8), Patriarch/Evangelist (Hebrews 7:4), Elder (James 5:14), Priest and High Priest (Hebrews 5:10, Hebrews 9:6-7).
Christ is the Head of the Church. (Ephesians 5:23, Mosiah 5:8)
So how can we know of ourselves which Church is True to the organization of Christ's Church?
Prayer. That's it. Prayer is the only way to know if any particular Church is right. Don't bother asking some mortal, even myself, because they will tell you as far as their understanding allows. God however cannot lie, and has all the understanding of the Universe. He is also your Heavenly Father and you can Trust Him without any reservation.
When Pocahontas goes to speak to 'Grandmother Willow', she seeks guidance. This represents prayer. The Spirit, like the Spinning Arrow guides us in Truth, and tells us what we should do. Once we know the path we need to have the courage to run the course. Much as Pocahontas could have received her revelation that she should save John Smith, had she not run as fast as she could to save him, or in other words to Live the Gospel, then he would have been killed by her father, and many others would have been killed in war.
Search the Scriptures, for in them ye find direction. Pray to your Heavenly Father and He will give you direction, but you must listen with your Heart.
