But through the advice and help of doctors, through a strong and determined effort, and through prayer, a soul can overcome this handicap.
(Shoghi Effendi, Lights of Guidance, p. 365)

Certainly the problem confronting you is a difficult one. However, its solution lies within your power, for Bahá’u’lláh has assured us that God “will never deal unjustly with anyone, neither will He task a soul beyond its power.” And again, “Whensoever he hath fulfilled the conditions implied in the verse: whoso maketh efforts for Us, he shall enjoy the blessings conferred by the words: ‘In Our Way shall We assuredly guide him"‘. You can be confident that with the help of doctors, by prayer and meditation, by self-abnegation and by giving as much time as possible to serving the Cause in your community you can eventually succeed in overcoming your problem.

If you are sincerely intent on overcoming your problem, you must yourself determine to resist wayward impulses each time they arise and the House of Justice feels that there is no better way than to turn to the Writings to divert our thoughts into spiritual channels , perhaps to concentrate on what we may do to help others along the way to discovering the Bahá’í Faith. The more we occupy ourselves with teaching the Cause and serving our fellowman in this way, the stronger we become in resisting that which is abhorrent to our spiritual selves.

In attempting to reconcile what may appear to be conflicting obligations, it is important to understand that the Bahá’í community does not seek to impose its values on others, nor does it pass judgment on others on the basis of its own moral standards. It does not see itself as one among competing social groups and organizations, each vying to establish its particular social agenda. In working for social justice, Bahá’ís must inevitably distinguish between those dimensions of public issues that are in keeping with the Bahá’í Teachings, which they can actively support, and those that are not, which they would neither promote nor necessarily oppose. In connection with issues of concern to homosexuals, the former would be freedom from discrimination and the latter the opportunity for civil marriage. Such distinctions are unavoidable when addressing any social issue. For example, Bahá’ís actively work for the establishment of world peace but, in the process, do not engage in partisan political activities directed against particular governments.

The Bahá’í Writings state that marriage is a union between a man and a woman and that sexual relations are restricted to a couple who are married to each other. Other passages from the Writings state that the practice of homosexuality is not permitted. The teachings of Bahá’u’lláh on personal morality are binding on Bahá’ís, who strive, as best they can, to live up to the high standards He has established.

The House of Justice was sorry to learn from your letter that your son has recently informed you that he is a homosexual. It commends your attitude of compassion and your efforts to both maintain harmony in your marriage and to keep open the lines of communication to your son.
(The Universal House of Justice, 1993 Jun 05, Homosexuality, p. 10)

With respect to your question concerning the position Bahá’ís are to take regarding homosexuality and civil rights, we have been asked to convey the following. The purpose of the Faith of Bahá’u’lláh is the realization of the organic unity of the entire human race, and Bahá’ís are enjoined to eliminate from their lives all forms of prejudice and to manifest respect towards all. Therefore, to regard those with a homosexual orientation with prejudice or disdain would be against the spirit of the Faith. Furthermore, a Bahá’í is exhorted to be “an upholder and defender of the victim of oppression", and it would be entirely appropriate for a believer to come to the defense of those whose fundamental rights are being denied or violated.

You write that you cannot explain to a friend why her way of love, homosexual love, is wrong and that your lack of understanding on this point also hampers your teaching efforts. Until there is wide recognition of Bahá’u’lláh as the Revealer of the Divine Will, there is no answer that will satisfy all questioners, particularly one who has a vested interest in maintaining that his behavior is innocuous. Homosexuality has been forbidden by Bahá’u’lláh in His Book of Laws, just as it was forbidden by other Prophets of God.
