They are born sinners. Otherwise, we wouldn’t baptize them.
Stay on topic Per Crucem. We are not discussing “born” into sin.
we are discussing
Sola Scriptura in so far as it relates to YOUR literal
translation of “all HAVE sinned”.
As in everyone everywhere has actually committed sin.
Because you have that bothersome “have” which implies
action and there does not appear to be the
counterpart of “what I really meant to say is that if
they have not actually sinned, well they were born into it
or would have.”

correct?
Years ago I taught many special Ed classes in California.
At a time when all of my 14 year old students were
severely retarded and autistic because their Cambodian
mothers had been bombed with Agent Orange during their
pregnancies. And all of these 14 year olds were pretty
much vegetables. They could walk, climb trees, feed themselves
and the autistic ones could unravel their jeans in
ten minutes from one single thread. Yet they didn’t know
even the word Mama much less Jesus Christ.
And they most certainly could not read the Bible
or anything else and would not have understood
one word if it was read to them. I was in fact able in
a partnership with MacDonalds, vocationally train
the ones that didn’t drool to put all the toys in Happy
Meal bags which they were eventually hired to do.
What sin do you suppose these kids could actually
HAVE committed?
None of them were baptized as the parents were Buddhists.
Are they damned and not “eligible” for salvation?
