He wishes me to tell you that he regrets extremely the sorrow that has come into your life, and that he agrees with all you have stated in general on the subject of divorce.

There is no doubt about it that the believers in America, probably unconsciously influenced by the extremely lax morals prevalent and the flippant attitude towards divorce which seems to be increasingly prevailing, do not take divorce seriously enough and do not seem to grasp the fact that although Bahá'u'lláh has permitted it, He has only permitted it as a last resort and strongly condemns it.

The presence of children, as a factor in divorce, cannot be ignored, for surely it places an even greater weight of moral responsibility on the man and wife in considering such a step. Divorce under such circumstances no longer just concerns them and their desires and feelings but also concerns the children's entire future and their own attitude towards marriage.
