Our good works can never satisfy in any way or in any way merit anything. Christ death on the cross satisfied once and for all our sin debt. This does not give us a license to sin, but it is He and He alone who is worthy.
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Eph 2:9 Not of works, lest any man should boast. Eph 2:10 For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
We are saved to do good works, not saved by good works.
You are mistaken. Works cannot merit the grace itself of justification (i.e. the transfer from the state of sin to the state of grace). But they can merit an increase in grace and eternal life for those in the state of grace who obey God. That's Catholic dogma. To deny that is heresy.
Council of Trent, Decree On Justification, Chap. 16: "... we must believe that nothing further is wanting to those justified to prevent them from being considered to have, by those very works which have been done in God, fully satisfied the divine law according to the state of this life and to have truly merited eternal life."
Council of Trent, Canon 32 on Justification: "If anyone says that the good works of the one justified are in such manner the gifts of God that they are not also the good merits of him justified; or that the one justified by the good works that he performs by the grace of God and the merit of Jesus Christ, whose living member he is, does not truly merit an increase of grace, eternal life, and in case he dies in grace, the attainment of eternal life itself and also an increase of glory, let him be anathema."
