I would like to see your support for understanding that any unmarried woman of any age and any child without support would be considered a widow or orphan.
It’s a cultural reality, in today’s world, most of the women in need of care from the church are the younger divorcees or unmarried mothers. That group is more likely to need help from the Stephen Ministries or other Deacon related church support than true widows, who in our modern society, if they remained married long enough to be widowed, are much more likely to be financially stable. The rerverse was true in Biblical times. So, to answer, my support is common sense plus historical metamorphisis.
