You were concerned with the “male child” part. I posted the NIV translation I was using in which “male child” appears.
After the ascension, when did Mary hide in the wilderness for 1260 days?
Where is the bible account of it?
The natural reading of it is that there is the ascension of Christ (v.5), an exile of Mary for 1260 days (6) and then the assumption (14). The span of time since the assumption that she is to be taken out of Satan’s reach is given in imprecise terms because that is the era still continuing, till the Second Coming of Christ of which hour we are not to be informed.
There could, I am sure, be other ways to read this, — there are certainly readings that complement this and give us a view of the Church Militant, and I am not wholly unsympathetic to the reading of Israel into that — but for anyone who asks where the Church found the assumption of Mary, that is the answer.
