After consulting my Moderator's Handbook (5th Edition) and searching out precedents from the past 100 years, I have come to the determination, that your use of the word "amen", is acceptable when used as you have used it, in the transitive verb form. According to Webster's Dictionary (online version), when amen is used as a transitive verb, one of it's meanings is:
to concur in heartily or emphatically and it is often used in the English language, colloquially. However, if it is used in the middle of a sentence and capitalized, it is often considered as having a religious connotation.
In deciding this matter, I have noted that you have capitalized the word. Also, since you have provided punctuation at the end of the word, so it has to be considered a one word sentence, where the beginning, middle and end of the sentence are one. Therefore, your word can be considered to be in the middle of the sentence and capitalized. However, since you used all capital letters, it may be determined from context, that your use of capital letters was for emphasis and not reverence.
All things considered, I deem your use of the word "AMEN" in your post to be acceptable under the standards of this board. This ruling applies only to this individual post and subsequent quotes of it and should not be misconstrued to mean that the use of the word "amen" is acceptable in any other post and such use of the word shall be judged on an individual basis.
