Why this examination? We'll let the INC answer this question:

"...all religious people should be stirred to inquire about the status of preachers in their respective churches. It is their bounden duty, for the sake of their souls, to ascertain if the founder or leader of their church was sent by God or not."

Pasugo, June 1970, page 6

"The right to preach the Gospel comes from God, not from any man or any human institution. It is the people's privilege and right to question the authority of anyone preaching the gospel".

Pasugo, January 1963, page 39

It's our privilege and right to examine the claims of the INC; our eternal destiny lies in the balance.
