November 7. On this date in 1957, Leroy Ioas sent a letter on behalf of Shoghi Effendi to Lea Nys of the National Spiritual Assembly of the Benelux Countries, warning her about an individual who "has known of the Cause for many years and has not seen fit to associate himself with it. Now that there may be some gratification in being Bahá’í, and some personal benefits to be gained, he will seek to associate with the Friends. However, they should avoid him in every way."

110: National Spiritual Assembly of the Benelux Countries, Mrs. Léa Nys, Secretary, 7 November 1957
Dear Bahá’í Sister:
Referring further to your letter of recent date with regard to Mr. [...], who has called on you in Brussels.
The Guardian feels that you and all of the friends should avoid Mr. [...]. He has known of the Cause for many years and has not seen fit to associate himself with it. Now that there may be some gratification in being Bahá’í, and some personal benefits to be gained, he will seek to associate with the Friends. However, they should avoid him in every way. Will you please send a copy of this letter to the Paris Spiritual Assembly telling them of the situation and asking them to properly inform the individual who wrote the letter of introduction in behalf of Mr. [...].With loving Bahá’í greetings, I am faithfully yours, Leroy Ioas
P.S. This is one of the few letters I received instructions from the Guardian to write shortly before his Ascension.
