Which enlightenment idea is expressed in this excerpt from the declaration of independence?

You didn't provide the excerpte, but the Declaration of Independence's strong overall theme is that people are born with natural rights.

Perhaps the most memorable phrase from the Declaration is this: "We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."

It is also the case that the Declaration of Independence supports the idea that government's power should be determined by the people. The very next words in the Declaration assert, "To secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed."

The founding fathers of the United States had adopted ideas about natural rights and the people's sovereignty from Enlightenment philosophers like John Locke (of England) and Baron de Montesquieu (of France).

the catholic church withhold people's access to the bible during the middle ages.

people could go to church and listen to the teachings, but it was absolutely forbidden to own and/or read the books of both the old and new testaments. it was also prohibited to translate the books (which where originally in biblical hebrew) to any other language.

this was done so the church could remain in control of what their teachings were and to enhance their importance and power, while also being able to judge people's actions through information that was unavailable for the general public.

the committees of correspondence were the american colonies’ means for maintaining communication lines in the years before the revolutionary war. in 1764, boston formed the earliest committee of correspondence to encourage opposition to britain’s stiffening of customs enforcement and prohibition of american paper money. the following year, new york formed a similar committee to keep the other colonies notified of its actions in resisting the stamp act. in 1773, the virginia house of burgesses proposed that each colonial legislature appoint a committee for intercolonial correspondence. the exchanges that followed built solidarity during the turbulent times and bring about the formation of the first continental congress in 1774.
