John 20:28 Thomas said My Lord and my God.
Irish, John's Gospel was the last written, about 60 years after Christ, at the very end of the 1st century. The earlier Gospels, written about 20 years before, do not mention his divnity. That is a considerable gap, especially in context where the Church was at those times.
You are reading the Book out od context.
And you, apparently, are reading the book with NO context.
Either it is the word of God, or it is the word of man.
So what you are saying is that since John was written 20 years after the others, we can ignore everything in it, right?
