I have a question for Roman Catholics does Ephesians 2:8-9 teach faith alone?

Roman Catholics Christians reject the concept of faith alone (ie that we are justified solely by our faith in Jesus Christ) and that we are justified by both our faiths and our works, but how do they interpret Ephesians 2:8-9 which clearly teaches faith alone? > For by grace are ye saved through faith; and that not of yourselves: > it is the gift of God: > > Not of works, lest any man should boast.
