The reason: serious differences with the news agency’s sponsor, the Legionaries of Christ. Details, from Catholic News Service:
Spanish journalist Jesus Colina, who established Zenit in 1997 and helped build it into a seven-language agency with about 450,000 email subscribers around the world, said he had been asked to resign because he resisted pressures to identify the agency and its work more closely with the Legionaries order.
Colina made the announcement in an email sent to Zenit personnel Sept. 28. A spokesman for the Legionaries of Christ, Father Andreas Schoggl, confirmed Sept. 29 that Colina was leaving and said Zenit planned to publish a message to readers explaining the move.
Colina said one issue of contention was that Legionary officials were less than candid with Zenit about the facts regarding the scandal surrounding the late Father Marcial Maciel Degollado, founder of the Legionaries, who was discovered to have sexually abused seminarians and fathered children.
Colina said his resignation was requested by Legionary Father Oscar Nader, the new president of Zenit’s governing council. The reason given, Colina said, was that “my activity in the world of Catholic communications does not demonstrate the institutional dependence of the agency on the congregation of the Legionaries of Christ, an identity that will from now on be underlined.”
