We are non-denominational but the whole Bible is our mandate. The Bible is the authentic word of God. All scripture is given by inspiration of God and is profitable for doctrine, for reproof, for correction, for instruction in righteousness.
2 Timothy 3:16
And the multitude of them that believed were of one heart and of one soul: neither said any of them that ought of the things which he possessed was his own: but they had all things common. Acts 4:32
As every man has received the gift even so minister the same one to another as good stewards of the manifold grace of God. 1 Peter 4:10
Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you, and lo I am with you always, even unto the end of the world. Matthew 28:19-20
