I agree the deffination of Apostle is the one who sent out to Go and Spel Gospel
An Apostle sets order in the house.
All of the statement I agree with they are sent out also and to set Godly order in the house .
I thought an Apostle was one who was in the present of THE LORD JESUS HIMSELF, or have had and Road of Damascus EXPERIENCE as Paul did. We have the complete WORD OF GOD AS HE WILL FOR US TO KNOW. There is no other foundation that we can build on except that which has been laid.
