Take a look at the time and age when the 'canonized saint' lived.  We don't speak the  "Middle English" of Chaucer any more.  We don't speak English as Shakespeare did.  We don't use the same expressions as was used in the Victorian age.  Why aren't we able to use 
"Godself' today.  God is not a white guy in the sky.  Maybe your 'autocorrect' [which isn't Christian, never mind Catholic], needs up-dating.  

If you think that God is from the past and only is comfortable with how we USED to refer to God----you are forgetting that God's name is "I AM" [the PRESENT], not "I WAS" [from the PAST].
