I was a little unsure Jcc that we Baha’is teach “Mary and Joseph had children together afterwards” but did find a reference:
- Christ’s Brothers and Sisters Born Natural Way
“We believe that **Christ only was conceived immaculately. **His brothers and sisters would have been born in the natural way and conceived naturally.”
(From a letter written on behalf of the Guardian to Dr. Shook November 19, 1945: Bahá’í News, No. 210, p. 3, August 1948)
Code:
(Compilations, Lights of Guidance, p. 489)
But I don’t know that it suggests “Mary and Joseph had children together afterwards…”
There were traditions that Joseph may have had children from a prior marriage or that there were cousins involved.
For Baha’is it’s not an issue so much… as in the Qur’an Jesus birth was miraculous.
