1 Timothy 6:10

It's a really well-known saying, but does the Bible actually say "Money is the root of all evil"? Only if you're experiencing a Mandela Effect, because what it actually says is "The love of money is the root of all evil". There are many who will argue the idea is flawed anyway, for example money is needed to build orphanages, to feed the poor and to build churches, so oversimplifying to such a level is absurd.

Here's the full entry from the King James 1611 edition:

For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows.

-- Timothy 6:10

Emphasising the love of money, rather than money itself, often comes as quite a surprise to many people when they hear of this.

Man cannot server both God and Mammon

When Jesus said "Man cannot server both God and Mammon" he was referring to the false God of riches and avarice. The worth of a man nowadays is always measured in money, not in other terms such as spirituality, professional skill or other aspects such as how fit he is.

There's a slight variation in the New International version of the Bible where it says "For the love of money is the root of all kinds of evil". Also, this isn't the only place the Bible covers this idea - many are aware of it saying it's "easier for a camel to pass through the eye of a needle than a rich man to enter the kingdom of God."

Orthodox Christians do class the love of money as a sin, but still acknowledge it's the misuse and greed which is the sin, not the actual spending when it's done for good.
