Do you doubt the Holy Spirit is sent to individuals? Was Jesus speaking only to the Apostles or is He giving comfort and instruction to you and me personally?
And I will pray the Father, and he shall give you another comforter, that he may abide with you for ever; Even the Spirit of truth; whom the world cannot receive, because it seeth him not, neither knoweth him: but ye know him; for he dwelleth with you, and shall be in you. I will not leave you comfortless: I will come to you." John 14:15-18 "If ye love me, keep my commandments.
Does Jesus only come to you through your church or does He come to you directly?
i doubt sincerely that every joe who says he's guided by the Holy Spirit is. having seen protestant parishes split over differences in interpretation i doubt it doubly so if theres a 'bible study group' involved.
