They aren't listed in the Bible, but they definetly weren't made up by Dante

https://en.m.wikipedia.org/wiki/Seven_deadly_sins#Origin_of_the_currently_recognized_seven_deadly_sins

but it is ultimately completely pointless. someone(or rather many someones) made up the OG bible canon and some fanfics are becoming almost canon by being well known. same difference

The term isn't found in the bible,but there are plenty of references to the sins.

Mark 7:20-23 (NLT) 20 And then he added, 'It is what comes from inside that defiles you. 21 For from within, out of a person’s heart, come evil thoughts, sexual immorality, theft, murder, 22 adultery, greed, wickedness, deceit, lustful desires, envy, slander, pride, and foolishness. 23 All these vile things come from within; they are what defile you.'

Proverbs 6:16 - 19 (KJV)

These six things doth the LORD hate: yea, seven are an abomination unto him:

A proud look, a lying tongue, and hands that shed innocent blood

An heart that deviseth wicked imaginations, feet that be swift in running to mischief

A false witness that speaketh lies, and he that soweth discord among brethren

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.

Yeah, they aren't biblical, basically just Christian fanfiction
