From the article you sourced:
>>Rubin’s ( the principle source of the claim) carry some weight, because he is the one of the two individuals who co-authored the only authorized biography of the current pope, entitled The Jesuit, published by Ediciones B in 2010. The biography was based on conversations with Bergoglio.<<
>>The claim has been seconded by homosexual activist Marcelo Marquez, who told the Times that Bergoglio “told me that homosexuals need to have recognized rights and that he supported civil unions, but not same-sex marriage.”<<
Why would Cardinal Bergoglio authorize a biography of himself if it had false statements about his support for homo civil unions?
He was a) misunderstood, b) misrepresented, or c), poorly catechized...
“The claim has been seconded by homosexual activist Marcelo Marquez”
Well hell I guess if a homosexual activist says its true it must be true. Now that carries a lot of weight.
No written transcript exists of Bergoglio telling someone that he agreed with homosexual unions. It is a heresay that has been debunked time and again.
