It is wrong to say that the catholic church teaches we are saved by faith+works. We don't believe that at all. As I said above, we can lose our salvation by what we do (sin), or fail to do (use our talents, charity, etc ..) but we are not saved by any work we do.
The Church teaches that faith with out works is dead and a dead faith can not save you.
We as a ppl were not redeemed by anything we as a ppl have done.
We as an individual were not redeemed by any work that we did.
We, personal and general have been redeemed by Christ offering Himself as an atonement for our sin, personal and original (general).
A person is saved by the grace this wrought. They are incorporated into this mystery through re birth.
Now that a person has been saved by grace, through faith in that atonement made as payment for their sins and not any works of perfection are they 'saved'.
But that faith that they have in that atonement must be a living faith in order for it to save.
What is a living faith? James clearly tells us. One that does good works, both spiritual and corporal works of
mercy.
Because where there is mercy shown, mercy will be given.
Because the way to be like God is to be merciful as He is.
Good works is not staying away from sin and it's not not following the commandments. That was the OT law, we are not under the law but grace.
We are now partakers of the divine life, so that means we are like God and if we truly have accepted Christ as Lord and savior, ie accepted His atonement for our sins, then we will not be pharisees striving to follow the law puffed up, full of ourselves but we will be like God, we will be
merciful.
That is the work we are to do if the faith we have in the atonement for our sins will be alive and not dead.
