How can we solve Christian unity?

Many in the East criticise the Official Relations between the Christian denominations. Ecumenism is understood as a pan-heresy…not a way forward, but a route of proselytism by the ‘heretical’ West. However, an interesting question is, how can we solve Christian unity, especially if we do not have dialogue with the other denominations? 

There are a number of answers to this question, depending on what each person believes. Nonetheless, it is a fact that we need to speak with one another without prejudice or any psychological ties to national identities. (The latter applies not only within Orthodoxy but also within certain churches in Protestantism or the Anglican Communion, such as the Church of England – which is a national church). When could this happen. Maybe, after the de-Christianization of the world we could reach unity due to the fact that necessity will force us to further listen to each other. When we reach this point, the arguments used have to come from a common tradition, i.e. the early church.
