The Pope is not orthodox. Rather, he is liberal and dissents from Cathotlic tradition and Canon law:
"On April 6, 1997, he recited the Credo without the Filioque on the occasion of the 1700th anniversary of the Constantinople I Council and on oecumenical occasions. (Eastern Catholic Life)
"In 1998, he gave communion, at a private Mass in the Vatican, to the late Rev. Sheila Brown, who had only shortly before been ordained an Anglican priestess and who, at that Mass, wore her "Roman" collar.
"In 1999, he gave communion to several Lutheran bishops who were his guests during a mass in the pope's private chapel in the Vatican. (London Tablet)"
The Pope is fully orthodox. He has taught no heresy. As for the first, omitting the Filioque is not the same thing as saying that the Filioque is wrong, after all, the original text adopted at Nicaea and Constantinople Councils did not have the Filioque. As for the others, I view them as scurrilous rumors, don't know if true or the full contexst, and even if they were true, errors of judgment or even sins do not justify disobedience to lawful authority in the Church.
