[Topic] Pope - Infallibility of [Orthodox] Papal Infallibility is rejected. The Holy Spirit acts to guide the church into truth through (for example) ecumenical councils. This Orthodoxy recognises the first seven ecumenical councils (325-787) as being infallible. [Roman Catholic] The Pope is infallible when, through the Holy Spirit, he defines a doctrine on faith and morals that is to be held by the whole church. This is a dogma and is therefore a required belief within Catholicism. [Protestant] 
Protestants also reject Papal infallibility. The only source of infallible teaching is that found in the Bible.
