The Constitution a Living Breathing Document, Why?

The constitution was written with each part having a meaning.  Those who voted on the constitution, whether they voted for or against, knew the meanings of each article and amendment.  There was great debate prior to voting, much of which was recorded.  By voting they agreed to accept the meanings.  The meanings were not to be changed.  They provided the avenue for change in the Amendment process and calling of a Constitutional Convention.  
Supreme Court judges were not to change the meaning of the constitution when looking at laws rather apply the known definitions.  We all know there where some opposed to this or that but they accepted what was laid before them by participating in the vote for the constitution and amendments.  So, when one say’s “yes but so and so was opposed to that principle” that is not germane to the argument of constitutionality, by voting they accepted the intended meaning.  
The reason the Constitution is a Living and Breathing Document is the Amendment Process and Constitutional Convention, NOT changing the meaning of words within the document!
