Withdrawal - from the Faith

Grieve thou not over those that have busied themselves with the things of this world, and have forgotten the remembrance of God, the Most Great. By Him Who is the Eternal Truth! The day is approaching when the wrathful anger of the Almighty will have taken hold of them. He, verily, is the Omnipotent, the All-Subduing, the Most Powerful. He shall cleanse the earth from the defilement of their corruption, and shall give it for an heritage unto such of His servants as are nigh unto Him.

Bahá’u’lláh, Gleanings from the Writings of Bahá’u’lláh, p. 207

If any soul speak ill of an absent one, the only result will clearly be this: he will dampen the zeal of the friends and tend to make them indifferent. For backbiting is divisive, it is the leading cause among the friends of a disposition to withdraw.

‘Abdu’l-Bahá: Selections From The Writings of ‘Abdu’l-Bahá, pp. 230-231

In a similar way, thou beholdest some women who have abandoned the Testament, and to them the bitterness of discord is sweet. They keep aloof from the Extended Shadow and dwell under the shade of a "black smoke." Alas for them and grief for them! They will surely lament and find themselves in loss. Verily, this is but an evident truth!

‘Abdu’l-Bahá, Tablets of ‘Abdu’l-Bahá v1, p. 130

If some of these isolated and inactive people gradually turn to other work than the Cause we should not always blame them -- they probably needed more help, more stimulating more teaching and Bahá’í comradeship that they received.

Shoghi Effendi, Lights of Guidance, p. 84

Just because some people have lost their vision of the Cause, or never had a proper grasp of its implications before entering it, and leave the fold, should not cause undue discouragement. There are bound to be such cases, and although every moral support should be given them, if they still wish to withdraw, they fall off -- as you said -- like withered leaves from the Tree of the Faith, and do it no real harm.

Shoghi Effendi, The Unfolding Destiny of the British Bahá’í Community, p. 448

Many of those who drift away from the Cause do so for the reason that they had ceased to go on developing. They became complacent, or indifferent, and consequently ceased to draw the spiritual strength and vitality from the Cause which they should have. Sometimes, of course, people fail because of a test they just do not meet, and often our severest tests come from each other. Certainly the believers should try to avert such things, and if they happen, remedy them through love.
