Scripture is silent about an awful lot of things but just because it doesn't specify something, doesn't give people license to make it up, assume it's true, and then teach it AS truth.
Saying that she could not have been bodily assumed, and that such a statement contradicts scripture is false.
Scripture says no such thing. Scripture doesn’t even comment on Mary’s life after Christ’s death beyond a solitary snippet in Acts.
There is so much information out there on the Early Church which is not contained in Scripture. Are we to regard all of it as false? Hardly. This is why Tradition is necessary.
I realise this is a radical statement, but the Gospels are the transmission of an oral tradition, years after Christ’s death and resurrection. The preservation of that oral tradition, both in the original books and in their later compilations, are why we are here today, arguing over the nature of those teachings.
None of this happens in a vacuum. Scripture AND Tradition complement each other. We cannot have one without the other.
