Matthew 7
12“In everything, therefore, treat people the same way you want them to treat you, for this is the Law and the Prophets.
According to the gospel preached by Jesus during His ministry, the above serves as the foundation for morality.
Over time the Golden Rule has similarly served as the foundation for morality across many cultures - both religious and secular.
