In the 1960s, largely through the ecumenical work of Archbishop of Canterbury Michael Ramsey and Patriarch [[Athenagoras I (Spyrou) I of Constantinople]], both the Anglican Communion and the Orthodox Churches established commissions to consider Anglican-Orthodox relations. Between 1973 and 1976 an "Anglican-Orthodox Joint Doctrinal Commission" met which led to the '''Moscow Agreed Statement''' which dealt with "the Knowledge of God, the Inspiration and Authority of Holy Scripture, Scripture and Tradition, the Authority of the Councils, the ''Filioque'' Clause, the Church as the Eucharistic Community, and the Invocation of the [[Holy Spirit]] in the Eucharist."
