I am sorry you felt insulted. In fact, from our perspective, refusing you Communion is an act of Love. First, had you been allowed to recieve Communion, it would have implied your consent to the doctrines of the Roman Catholic Church -doctrines you obviously do not accept. Hence, by denying you Communion, we preserved for you your own integrity.
Second, being non-Catholic, it seems probable you are ill-equipped to ascertain at this point whether you are worthy to recieve Communion. St. Paul warns that those who recieve Communion unworthily (ie by 'not discerning the Body and Blood) drink condemnation on themselves. Hence, it is out of concern for your own immortal soul that Communion is withheld.
I understand you won't accept these provisions, but from our standpoint they are necessary out of a concern for you.
Excellent explanation. Thank you.
