displaces sin? What, pray tell, are you talking about? Sin was dealt with once and for all by the atoning work of Christ. It is not "displaced" as you say ... "it is finished."
In the Corinthians passage you have a sequence of Aorist Middles ... i.e. past tense ... you have already been washed, you have already been sanctified, you have already been justified ... in fact, most of the passages you keep citing use Aorist or Perfect tenses ... past completed action.
This closes the case on your "faith + works" approach to salvation. If you want to continue trying to add what has already been completed and believe that you are making yourself more acceptable to God then do-so. My position in Christ is already determined based on HIS work ... not MINE.
However, actual sin is not finished. People do sin. Those who do sin, and do not have their sin sacramentally absolved, are not in a state of grace. Coversely, people can gradually free themselves of sin through faith and good works and are saved by grace that fills them. That process is described in 2 Peter 1. Grace displaces sin.
My position in Christ is already determined based on HIS work ... not MINE.
If you are baptized and believe everything Christ told you to do, -- for example, do good works, confess your sin, forgive others, receive the Eucharist, then that would be a complete Catholic faith which will save you in the end, when "by good works you may make sure your calling and election" and "you shall not sin at any time". You can start on that road by reading the Holy Scripture with love and attention, and stay away from Protestant lies. I wish you the best and pray for you.
