Shoghi Effendi wrote his last general letter to the western friends because he felt that the public should be made to understand the attitude the Bahá'í Faith maintains towards the prevailing economic and political problems. We should let the world know what the real aim of Bahá'u'lláh was. Up to the present Unity of Mankind was only of an academic importance. Now it is becoming more and more a subject for international statesmen to think of. It is coming to the field of practical politics. It is therefore a wonderful chance for us to come to the front and expound the teaching which is the goal and aim of the social precepts of Bahá'u'lláh. Shoghi Effendi hopes that the friends will re-echo this call to an organic unity of mankind until it forms part of the conscious faith of every living man in the world. Great judgement should be however practised lest we be misunderstood and our Faith be classed among radical movements.
