Epistemology is the philosophical theory of knowledge. It involves views of how knowledge is obtained, what knowledge is and what qualifies or does not qualify as genuine knowledge or truth.
"What is knowledge? How do we get it? Is certainty a necessary prerequisite of knowledge or can we know that the sun will rise tomorrow even if we are not one hundred per cent sure? How much of what we commonly believe deserves to be called ‘knowledge’
and how much of it is mere opinion? Is knowledge relative to a culture? Is all our knowledge derived through the senses or are there truths about the world we can know a priori? When we do perceive, do we actually make contact with 'the world?
Or do we only ever make contact with our own ideas? Are we fooling ourselves if we think we can know anything at all?"  These
are the types of questions that epistemology seeks to answer.
Scripturalism is a theory of epistemology in which the Scriptures, and deductions from the Scriptures, are the foundation of all knowledge. This theory rejects the idea that induction and senses are able to give knowledge. Knowledge is
often defined in Scripturalism as justified true beliefs.
