Pandemic october wedding

I have a big issue, as same as most of 2020 brides. I'm getting married on October 31st. I already reserved the Venue and the church. I haven't reserved anything else. I had to hold up a bit of the whole planning due to the virus pandemic. I had an estimate of 200 guest but now I'm not so sure what to do. I don't want to put anybody at risk, although there haven't been any guidelines for October yet, I don't know how prudent is to continue with the wedding, there is a speculation by scientists that there will be a second wave for the end of the year because of the flu season mixed with Covid.



My venue said that they are followings CDC guidelines, and that my event is open and free to happen, but the thing is I can't wait until August or September to postpone because I have international guest who have to travel,etc. In addition, some of my guest (mostly closest friend) are not sure if they can come to Houston because all Visa offices are closed and they canceled there Visa appointment.
This religous ceremony is really important for both my husband and I, and we have our thoughts about postponing the religious ceremony for another year. He suggests we do the religious ceremony and we can have our reception later.
This is so hard for me, because it was really challenging to come up with a date that most of our family could come (yes, more than 120 are family, we have big family trees)
I really need an advice or any comment. Thank you
