What is the best version of the Bible to be used? There are many versions of the Bible today and I am not sure what is to be used that is free from doctrinal errors and is authorized by the Church.
RSV-CE and /or the Douay-Rheims are my choices. I use the DRV most.
Here is a helpful article from Catholic Answers:
