Yep, I had a big problem with that as well.
Before Jesus, Abraham’s faith was counted as righteousness,
but AD, Jesus is THE Way, not A way.
When reading to my kids, I had to “correct” the doctrine of the idea that a follower of Tash was going to the same salvation as those who were followers of Aslan.
However, at the beginning of the book, when the false prophet and the false Aslan (anti-Christ) were being introduced, as well as the “ecuminicalism” heresy was being promoted by the antagonists, I was all over it, giving them the parallels we see in our world today.
Gal 3:8 - "Scripture foresaw that God would justify the Gentiles by faith, and announced the gospel in advance to Abraham: All nations will be blessed through you."
I Peter 1:20 - "He was chosen before the creation of the world, but was revealed in these last times for your sake."
Jesus has always been the only way. There never has been a Plan B.
Did you also "correct" what Christ said about the salvation of the Good Samaritan when you read Luke 10:25-37?
