“Another example is that Mormons believe that if a spouse dies - then they will be reunited in heaven. This is in error because Jesus said that we will neither marry or be given in marriage in heaven.”
You are correct in your scriptural reference, but i fear your interpretation is not exclusive of others: i.e., my take on that scripture is that marriages are an earthly ordinance which cannot occur once you have gone on to heaven, but i don’t see where it excludes folks married on earth from being together in heaven.
i believe that scripture goes on to say that those who don’t marry in this life will go on to be as angels of god in heaven.
The Bible says that we will know as we were known. I’m not sure if it means we will remember someone as having been our spouse or not. I might think so, however, that doesn’t mean that in heaven a couple will remain as a married couple.
I was referring to what the Mormons believe that they will be reunited in heaven in marriage to their spouses who have passed.
