Set your faces towards unity

O contending peoples and kindreds of the earth! Set your faces towards unity, and let the radiance of its light shine upon you. Gather ye together, and for the sake of God resolve to root out whatever is the source of contention amongst you....
 The difference between the ordinances under which they abide should be attributed to the varying requirements and exigencies of the age in which they were revealed. All of them, except a few which are the outcome of human perversity, were ordained of God, and are a reflection of His Will and Purpose. Arise and, armed with the power of faith, shatter to pieces the gods of your vain imaginings, the sowers of dissension amongst you. Cleave unto that which draweth you together and uniteth you.
This, verily, is the most exalted Word which the Mother Book hath sent down and revealed unto you. To this beareth witness the Tongue of Grandeur from His habitation of glory.
