Principle, not proof text. You also have no verse to say it started with Paul, so this is why there is a difference of opinion. Virtually all thinking Christian agree that the Spirit/Christ birthed the Church with Jew/Gentile one in Him after the cross. Waiting for Paul's conversion is not the issue. Paul's issue is a missionary calling to expand the gospel and flesh out doctrinal details systematically. The basis for the gospel is Christ who predates Paul (duh).
		
		
	 
 Hi , and I have written it many times and on many other sites !!
 SAUL  was called by Grace in Gal 1:15 !!
In Gal 1:15 , it reads , "  But when God was pleased , the one separating me from my mother's womb , having called  ( me )  by His Grace  ".
 #1 , The first  verb is  " pleased "  , EUDOKEO , and means  "  to choose ,  determine , decide , take pleasure in , perfer  !!
 #2 , The second verb is  " separated "  which is  APHORIZO  and means to  Mark off by Boundries  , to  Limit  , to Separate  !!
 #3 , The  third verb is ,  "  called  "  , which is  KALEO  ,  and means  " to call  , invite  , to call by name !!
 #4 , And verse 16 reveals why SAUL/PAUL  was called  , "  to reveal His  Son in me ".
 #5 , To preach  Him as the Gospel among Gentiles !!
 What was he , SAUL/PAUL  to preach , the Revelation of the Mystery , Rom 16:25  , Eph 3:2  and Col 1:25 !!
 We have proof texts , and you will not   QUOTE  your proof Texts , why not ??
 Are you Ashamed of your proof texts ??
 Do you have proof texts ??
 My proof texts ,  TRUMP  whatever you will produce , so lets have THEM ??  
 The 12 apostles were bound by Matt 10:6 ,  "  But  go rather to the LOST  SHEEP  of the House of Israel  ".
