uses the argument of the difference between petros and petra in Greek ("You are Peter [petros] and on this rock [petra] I will build my church.") The Eastern Orthodox and Oriental Orthodox churches see Jesus' words "whatsoever thou shalt bind on earth shall be bound in heaven" as bestowing first upon Peter what was later bestowed upon all of the Apostles collectively. The Orthodox believe in the infallibility of the Church as a whole, but that any individual, regardless of their position, can be subject to error. Ecumenical meetings among different denominations have taken place regarding these interpretations, but no final agreement has emerged. Commemorations The Roman Catholic Church celebrates the Feast of the Chair of St. Peter on 22 February in the General Roman Calendar. In the General Roman Calendar of 1960, the feast is celebrated on 18 January. Some Anglican and Lutheran churches celebrate the Feast of the Confession of St. Peter on 18 January. The Confession of Peter is the beginning of the Week of Prayer for Christian Unity, actually an octave rather than a week, and was originally known as the Octave of Christian Unity. It is an international Christian ecumenical observance that began in 1908. It spans from 18 January to 25 January (the Feast of the Conversion of Saint Paul).
