This book is ambiguous and could have used better explanatios. St Nicholas of Myra was a Catholic bishop, the book calls him a "pastor" which a bishop is but I think they should have been more specific, and then to make it worse they've included a glossary at the end which defines pastor as "a man called by God to a local congregation to serve the people there with the gifts from God: the preached Word, Baptism and the Lord's supper."
Which brings me to my next point: as a Catholic bishop he offered communion at the Holy sacrifice of the Mass. The book says "he gave them the Lord's supper.
To me, the worse part though as a Catholic, is the definition for Saint in the glossary: this is a word from the Greek language that means"holy one". A Christian is holy by faith in Christ, our Redeemer." A Christian is NOT holy only through faith. They must live according to God's laws and if they do commit a sin they must repent, confess their sins to a priest and then make penance for their sins in order to be holy, in addition to having faith. They must live out their faith, not just believe. Also in the definition of "the Lord's supper" they call it a celebration, when it's actually a sacrifice, the Holy Sacrifice of the Mass.
And in the notes to grown ups it says the story is somewhat fictionalized, which I'm guessing they are referring to the names and possible characters in the family which saint Nicholas helped by leaving dowrys for the girls but that's about it. Everything else did happen. In my opinion they should have made that more clear.
The pictures are beautiful and other than the the story is well told which is why I gave it 3 stars.
