There are those who believe the Church saves.
I believe Jesus Christ Saves.
There are those who believe men can deem a Church Sovereign based on history and a self determined infallibility.
We have in Scriptures that God is Alone Sovereign. His Words are infallible.
There are the differences.
there are those who try to separate Jesus from His Body, but then there is the Apostolic Faith that teaches the Church is the Body of Christ.
there is a difference. i would recommend reading Acts 9:4 to see how Jesus views the matter.
there are those who believe Jesus Christ saves outside the Church, then there are those who hold the Apostolic Faith that realize Jesus Christ Himself gave the Church the authority to make disciples by teaching and baptizing them. there is a difference. i would recommend reading Acts 8:26-39 to see the Apostolic Faith in action.
