We should strive for unity in understanding (which is one reason I’m on this forum) but lack of unity in understanding doesn’t spiritually separate those that truly have faith in Christ .
Agree. To have faith in Christ is to follow ALL of what Jesus taught, contained in fullness in the Church he established and has promised to lead to all truth.
I assume you copied and pasted the words of St. Clement from another website without reading the source document which can be found here:

He also says this, in the same Corinthian letter.
Chap. XXX. Let us do those things that please God, and flee from those He hates, that we may be blessed.
Seeing, therefore, that we are the portion of the Holy One, let us do all those things which pertain to holiness, avoiding all evil-speaking, all abominable and impure embraces, together with all drunkenness, seeking after change, all abominable lusts, detestable adultery, and execrable pride. “For God,” saith [the Scripture], “resisteth the proud, but giveth grace to the humble.” Let us cleave, then, to those to whom grace has been given by God. Let us clothe ourselves with concord and humility, ever exercising self-control, standing far off from all whispering and evil-speaking,
being justified by our works, and not our words.
To what you copied, he then says:
Chap. XXXII. We are justified not by our own works, but by faith.
Whosoever will candidly consider each particular, will recognise the greatness of the gifts which were given by him. For from him have sprung the priests and all the Levites who minister at the altar of God. From him also [was descended] our Lord Jesus Christ according to the flesh. From him [arose] kings, princes, and rulers of the race of Judah. Nor are his other tribes in small glory, inasmuch as God had promised, “Thy seed shall be as the stars of heaven.” All these, therefore, were highly honoured, and made great, not for their own sake, or for their own works, or for the righteousness which they wrought, but through the operation of His will. And we, too, being called by His will in Christ Jesus, are not justified by ourselves, nor by our own wisdom, or understanding, or godliness, or works which we have wrought in holiness of heart; but by that faith through which, from the beginning, Almighty God has justified all men; to whom be glory for ever and ever. Amen.
All of which is very Catholic. Works of the OT Law can not justify. Works of love do.
Which is why St James says:
24 You see that a person is justified by works and not by faith alone.
Which is consistent with his words of Abraham:
You see that faith was active along with his works, and faith was completed by works,
If you agree with the written Word of God above, you hold a very Catholic view, one supported by St. Clement.
