I am committed to the cause of Christian unity. I mean real unity, not the continuation of ecumenism. An Old Catholic priest (a rather young Old catholic priest) once asked me what I thought of "Churches Together". My answer was "not much". He lives in an ecumenical community and believes that he is practising unity (in some ways this seems to be correct). He was there with his Abbot (of the community) who is a Methodist. They both laughed and said that they call them "Churches Not Together" which is accurate. As a "Roman" Catholic I cannot accept that community's version of unity. There is more to unity than that. But at least those men really want unity and are not content with meetings, "shared worship" (an ugly phrase if ever there was one) friendly chatter, tea and biscuits etc, etc.
I realise now, more clearly than ever, that the majority of Christians outside the Catholic Church do not want real unity (or they think they already have it, which is worse). The "unity" of international, multi-denominational mutual recognition is NOT real unity - it is a sham. The unity that Christ prayed for is much more than this. This lack of a real desire for genuine unity - a unity of faith as well of friendship (though it begins with and is sustained in friendship) makes Christian unity week something of a bore. Christian unity week (or more accurately octave) serves to display the lack of commitment to, desire for, real unity. It is not a papering over cracks, but a failure to see the seriousness of those cracks - not cracks but fissures. Pope Francis rightly says that division is a scandal, but for many non-Catholic Christians division is not a problem because their vision of the Church is of a world-wide, multi-denominational group of people who call themselves Christians. For them there is no establishment or institution except the kind you like or want to create. For them Christ did not found a Church that would develop any real structure but a mass of people who sometimes disagree on things that some regard as essential and others judge to be unimportant. Is this the unity that Christ wanted and wants? Those who genuinely ponder John 17 cannot possibly believe this. After so long since the first Octave of Prayer we are no closer to a unity of faith and worship. The friendship stops at the altar steps.
