Thank you so much for your replies and offers of saved games.
I have discovered what I did wrong and it wasn
't a bug at all.
I was playing Hannah first than saved the game.
I then proceeded to play Sam and saved a second game.
This resulted in (I beleive) 2 games instead of one where you switch from one to the other.
I loaded the game where Sam was ready to cross over the walkway in front of the statue and switched over to Hannah and brought her to the tunnels and switched back to Sam and then it worked where I had the priest appear to me.
So I hope this helps anyone that wants to play this part over and has maybe done the same thing in error.
