Westminster Larger Catechism
Q. 60. Can they who have never heard the gospel, and so know not Jesus Christ, nor believe in him, be saved by their living according to the light of nature?
A. They who, having never heard the gospel, know not Jesus Christ, and believe not in him, cannot be saved, be they never so diligent to frame their lives according to the light of nature, or the laws of that religion which they profess; neither is there salvation in any other, but in Christ alone, who is the Savior only of his body the church.

Westminster Confession of Faith
Chapter 11: Of Justification
1: Those whom God effectually calls, He also freely justifies; not by infusing righteousness into them, but by pardoning their sins, and by accounting and accepting their persons as righteous; not for any thing wrought in them, or done by them, but for Christ’s sake alone; nor by imputing faith itself, the act of believing, or any other evangelical obedience to them, as their righteousness; but by imputing the obedience and satisfaction of Christ unto them, they receiving and resting on Him and His righteousness by faith; which faith they have not of themselves, it is the gift of God.
