Not everything that has a foundation in Christian faith tradition is worth keeping. It is not a perfect faith tradition.
Take the Christian faith tradition on women:
Ephesians 5:22 Wives, be subject to your husbands as you are to the Lord. 23 For the husband is the head of the wife just as Christ is the head of the church, the body of which he is the Savior.
1 Corinthians 11:3-7: But I want you to understand that Christ is the head of every man, and the husband is the head of his wife…For a man ought not to have his head veiled, since he is the image and reflection of God; but woman is the reflection of man.
As one commentator on Thomas Aquinas has pointed out:

Or how about slavery:
Titus 2:9-10: Tell slaves to be submissive to their masters and to give satisfaction in every respect; they are not to talk back, 10 not to pilfer, but to show complete and perfect fidelity, so that in everything they may be an ornament to the doctrine of God our Savior.
St. Augustine: “if you see your slave living badly, what other punishment will you curb him with, if not the lash? Use it: do. God allows it. In fact he is angered if you don’t. But do it in a loving rather than a vindictive spirit.” (Servumque ipsum tuum, si male viventem videris, non poena aliqua, non verberibus refrenabis? fiat hoc, fiat : admittit deus, imo reprehendit, si no fiat ; sed animo dilectionis fac : non animo ultionis.)
