Christ is not brought back down from Heaven by the priest to be sacrificed over and over and over and over again. We do not consume Christ as previously noted..
However, you are equally obliged to decline to participate in the Holy Eucharist in the Catholic Church, whether your reason is that you respect us or that you do not respect us.
I do not participate because it is not Scriptural.
Believe what you want, but do not misrepresent what Catholics believe.
You're fine when you tell me what you believe.
Do NOT misrepresent to me what I believe.
That does not show respect.
