Those thots have gone through my mind also, and I was encouraged to hear that when she was given communion Sunday night, that she was asked to try to say Jesus, and that she tried to three times.
Now that doesn't say she had accepted Christ as her Saviour when she was younger, but it was a confession of faith in Christ on a very basic level.
I've also prayed that if she hasn't before, that the Lord will still work in her heart, on whatever level her mind is still functioning.
As Catholics, we believe in one baptism for the forgiveness of sins....Terri was baptised, I'm sure of it.
