We are saved by Grace, but not faith alone.
What you call “works” are the visable sign of Christ’s Church on earth, the Catholic Church.
Jesus promised he would not leave us orphans (John 14:18) but would send the Holy Spirit to guide and protect us (John 15:26). He gave the sacraments to heal, feed, and strengthen us. The seven sacraments baptism, the Eucharist, penance (also called reconciliation or confession), confirmation, holy orders, matrimony, and the anointing of the sickare not just symbols. They are signs that actually convey Gods grace and love.
The sacraments were foreshadowed in the Old Testament by things that did not actually convey grace but merely symbolized it (circumcision, for example, prefigured baptism, and the Passover meal prefigured the Eucharist. When Christ came, he did not do away with symbols of Gods grace. He supernaturalized them, energizing them with grace. He made them more than symbols.
God constantly uses material things to show his love and power. After all, matter is not evil. When he created the physical universe, everything God created was “very good” (Gen. 1:31). He takes such delight in matter that he even dignified it through his own Incarnation (John 1:14).
During his earthly ministry Jesus healed, fed, and strengthened people through humble elements such as mud, water, bread, oil, and wine. He could have performed his miracles directly, but he preferred to use material things to bestow his grace.
In his first public miracle Jesus turned water into wine, at the request of his mother, Mary (John 2:111). He healed a blind man by rubbing mud on his eyes (John 9:17). He multiplied a few loaves and fish into a meal for thousands (John 6:513). He changed bread and wine into his own body and blood (Matt. 26:26 28). Through the sacraments he continues to heal, feed, and strengthen us.
We are saved by faith, not by works, lest any man should boast. The object of faith is not in ourselves as a work, but it is in Christ and His work on the Cross. So that saving faith which is nonmeritorious for us, is focused upon Him.
We also are saved by Grace, but the Grace by God is directed at those whom He gives eternal life. He is not bound to give us that gift, but it is by grace on His behalf that he directs it at us.
The direction and active agent in faith and grace are different directions, although just as He has acted by Grace towards us, we also are to exercise grace towards others through faith in Christ.
