By far the most likely ID is Rosa multiflora. There are guides on the web to help with a positive ID. If you look closely at the base of the leaf, where it attaches to the cane, there are little wings called stipules. Multiflora, and its garden hybrids, have fringe on those stipules looking rather like eyelashes. None of the native roses have that characteristic.

I love the variegation.

Mamaham, I'm the one who posted the thread linked above by floral. Like you, I thought it was such a beautiful plant, but quickly learned how aggressive it is. Also, like you, my property backs up to a green belt. We bought the property a few months ago and I noticed the small patch of arch angel and thought how pretty it was. Fast forward five months, and it was starting to choke out everything in its path. That's when I noticed how badly behaved it was and started doing some research. You do not want this plant growing in your yard. Whatever you have to do (pull it, spray it, burn it), just get rid of it somehow. The first time I sprayed it, it didn't even flinch. Almost three weeks later, I sprayed it again with a stronger dose and it's finally started to wilt, although when I went out there this morning, there were shoots standing tall and proud. I'm pretty sure I'll have to spray it as least once more and I wouldn't be surprised if it takes several more sprays to be rid of it. At this point, I feel like I have a good chance of winning this battle, but I'm reminded of the old saying, "never turn your back on the waves." There is a part of me that thinks I'll never be completely rid of it, but now that I've beat it down, I may have a chance at keeping it under control. My main goal is to keep it from spreading into the green belt behind my house as it will choke out the native plants and has the potential to cause food shortages for the wild life as it competes with the native plants that are their food. Ugh!
