Is the church going to stop him if he goes to the RCC for mass?
Maybe I will walk up to my local Catholic church and take part.
It isn't like they are going to know I am Protestant.
What are they going to do, throw me out?
I am a believer in Jesus Christ. I have a right to communion, even though when I arrive, I will know your version to be incorrect Biblically.
Why do you think you have a "right" to Communion in a Roman Catholic church if you do not believe in RC teachings?
"I am a believer in Jesus Christ. I have a right to communion, even though when I arrive, I will know your version to be incorrect Biblically."
How do you KNOW these things? Calvin said so?
As for coming to a Catholic service, be welcome. Study and learn. If you attend daily services, the ENTIRE Holy Writ (including the parts Luther and Calvin tossed out) will be read aloud to you. Pretty bold if the Church didn't believe the BIBLE was being followed, wouldn't you say? As for the laity, well, don't you think they would notice?
There is a reason the Catholic Church is the largest as well as the oldest (and original holding that faith intact for 2,000 years) of denominations calling themselves "Christian".
Here are some tests for you:
When did your denomination accept abortion as licit and why?
When did your denomination accept birth control/contraceptives as licit and why?
When did your denomination accept divorce as licit and why?

Well, you could always receive communion while pretending to be a Catholic.
But, if you made a point of making known where you stood on the matter and then got in to communion line anyway, I would expect the priest to simply deny it to you.
What are you going to do then?
If you answer involves anything to the affect of forcing yourself physically or disrupting the mass... you'd be out on your ass before you knew what hit you.
