Ut Unum Sint §70

⁷⁰ This difficult and delicate research, which involves questions of faith and respect for one's own conscience as well as for the consciences of others, has been accompanied and sustained by the prayer of the Catholic Church and of the other Churches and Ecclesial Communities. Prayer for unity, already so deeply rooted in and spread throughout the body of the Church, shows that Christians do indeed see the importance of ecumenism. Precisely because the search for full unity requires believers to question one another in relation to their faith in the one Lord, prayer is the source of enlightenment concerning the truth which has to be accepted in its entirety. Moreover, through prayer the quest for unity, far from being limited to a group of specialists, comes to be shared by all the baptized. Everyone, regardless of their role in the Church or level of education, can make a valuable contribution, in a hidden and profound way.
