What “Amen” Means When Receiving Holy Communion: The word “amen” is actually quite significant, and even more so when declared in response to the minister’s words when presenting the host. It’s not just the final word in a prayer, it has a meaning.
“Amen” is derived from Latin, which was derived from Greek, Which was derived from Aramaic, which may have been derived from Hebrew. Essentially, it is an affirmation of the truth in something preceding it, or it can be a heads up that what you are about to say is the truth (Amen, amen, I say to you…”). It is a declaration of something that is true or something you whole heartedly agree with.
When you say “Amen”, you are declaring your emphatic agreement with something. In this case, you are agreeing with the teachings of the Catholic Church; not only in respect to the Eucharist, but to all of the teachings of the Church, and that you also strive to live your life like you mean it. And you are testifying that, to the best of your knowledge, there are no impediments to you properly partaking of the Eucharist. In short, that you are in full communion with the Church.

And , indeed, you are. One way or another.
