Yes it is.
“Then said they unto him, What shall we do, that we might work the works of God? Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.” John 6:28-29
Do you truly believe that just “believing” is enough?
Works are the evidence of faith. I do not believe one can separate one from the other. The Catholic Churches do not teach that one can work one’s way into heaven. That is a misconception many protestants have.
