Once for all Christ gave to the church the unity and the truth which are his. Yet through the centuries the church is sent to grow into the perfect apprehension of the truth, and to realise perfectly a unity which is to be wrought out amid the diversity of nations and cultures, and of temperaments and religions and intellectual experiences.

The ecumenical task is rightly never to be described as if it were like the reconstruction of a toy once made in its completeness and subsequently broken. Had there been no quarrels in the Church of Corinth, no schisms in the church, no great schisms between East and West, there would still be the growth through years of spiritual and intellectual struggle into the fullness of the unity which Christ once gave.
