Earlier quoted context omitted.
Read the Talmud. Then proceed to read the Church Fathers through to the scholastics. Add Justinian for good measure. The roots of (real) liberalism are all there in these largely theological treatises including the inalienable right of the people to revolt against the state when it becomes tyrannical (see Juan de Mariana).
thanks for the reply, its appreciated but as someone who has only passing familiarity with those, is it possible to provide a list (for example) without having to read all those first?
But what I recall was the general idea that God alone was perfect, man is sinful and corrupt, therefore we should limit the power of the state as much as we can because of the extra powers it has over everyone else. The divine law being above worldly law, so even rulers have a ruler, and shouldn't become tyrants over their people. Those ideas, while not applied perfectly, must've had some influence.
