Most are derived from Psalms, Proverbs, and other locations in the old testament. It came from Catholicism. The weakest of the seven for a Biblical origin is Sloth, as it is derived from a failure to act in line with scripture. The list itself is not of canonical origin but is instead a collection of thoughts in a simplification that is easier to digest and remember.

There is some value in the scripture when it comes to philosophy, however small that may be. It is a great example of what humans were able to directly observe in their time, the ways humans were manipulated with their vulnerabilities, how politics and religion were the same thing in past eras, and many other minor intrigues. Still, 99% of life that has ever existed has gone extinct, and there is not a single reference in scripture that reflects ontological knowledge of the universe. Every bit of every religious work around the world can be explained by human observations and meddling. If a God exists, the least they could have done is prove their existence by giving any of the cosmological constants that are the fundamental building blocks of the universe, or act like a sane person and give me a call any time - my phone is on. Faith is a synonym for fantasy, and primarily persists because of religious isolationist social networking, and teaching faith to gullible children before they have a choice in their social networking development path.
