The ecumenism was also commended by the Pan Orthodox Synod from Moscow in 1948.
“In view of the fact that: the aims of the ecumenical movement which have expressed themselves in the organization of the Ecumenical Council of Churches with the ultimate goal of organizing an ‘ecumenical church’ on the present stage do not correspond to the Christian ideal and the aims pursued by the Church of Christ as understood by the Orthodox Church […]
The Consistory of the Primates and Representatives of the Orthodox Autocephalous Churches, noting the present state of affairs and prayerfully calling upon the cooperation of the Holy Spirit, has decided: To communicate to the Ecumenical Council of Churches in response to the invitation received by all of us to participate as members in the Amsterdam Assembly, that all the local Orthodox Churches participating in the present Consistory are obliged to renounce their participation in the ecumenical movement on its present form”
