While it can be a severe test to a Bahá'í to see fellow believers violating Bahá'í laws or engaging in conduct inimical to the welfare and best interests of the Faith, there is no fixed rule that a believer must follow when such conduct comes to his notice. A great deal depends upon the seriousness of the offence and upon the relationship which exists between him and the offender.
If the misconduct is blatant and flagrant or threatens the interests of the Faith the believer to whose attention it comes should immediately report it to the Local Spiritual Assembly. Once it is in the hands of the Assembly the believer's obligation is discharged and he should do no more than pray for the offender and continue to show him friendship and encouragement - unless, of course, the Spiritual Assembly asks him to take specific action.
Sometimes, however, the matter does not seem grave enough to warrant reporting to the Spiritual Assembly, in which case it may be best to ignore it altogether. There are also other things that can be done by the Bahá'í to whose notice such things come. For example he could foster friendly relations with the individual concerned, tactfully drawing him into Bahá'í activities in the hope that, as his knowledge of the teachings and awareness of the Faith deepens, he will spontaneously improve his patterns of conduct. Or perhaps the relationship is such that he can tactfully draw the offender's attention to the teachings on the subject - but here he must be very careful not to give him the impression of prying into a fellow-believer's private affairs or of telling him what he must do, which would not only be wrong in itself but might well produce the reverse of the desired reaction.
If a believer faced with knowledge of another Bahá'í's misconduct is unsure what course to take, he can, of course always consult his Local Spiritual Assembly for advice. If, for some reason, he is reluctant at that stage to inform his Spiritual Assembly, he can consult an Auxiliary Board member or Assistant.
Whatever steps are taken, it is vital that the believers refrain from gossip and backbiting, for this can only harm the Faith, causing perhaps more damage than would have been caused by the original offence.
