I read that Leslie Dixon Weatherhead, an English Christian theologian, made every effort to present Mary as a very pure, sincere, immature, young maiden who simply had interpreted the Angel's Annunciation as a divine instruction to stay for three months with her cousin's husband, Zechariah, and that was when Jesus was conceived.
Then, excluding the case that Leslie was either a crazy man or an illiterate man, which doesn't seem true, on which parts in the gospels is Weatherhead's argument about Mary, mother of Jesus, founded?
