The reason I'm thinking that there's a relationship is the Europeans seemed to have two major priorities when conquering the Americas looking for loot and imposing Christianity.
It seems like after running out of easy to find loot in the Americas, they used the wealth from that loot to start the transatlantic slave trade, and here again the slavers frequently used Christianity to justify subjugating non-christian populations.
I saw an argument suggesting that funding Columbus was an example of an early capitalist like activity.
The already rich Spanish royalty used their wealth to fund Columbus' high risk, high return venture in a way similar to more modern venture capitalism.
They lacked the legal advancements of the limited liability joint stock corporation, so it's not as developed as modern capitalism, but does arguably represent a capitalist like enterprise.
I think most people would agree that later ventures enterprises like the Northwest Territories company or the East India company were quite similar to modern capitalist companies and were major implementers of colonialism.
Christianity, colonialism, and capitalism are major themes in western history, and they all intertwined with each other in ways that my understanding of history is inadequate to tease apart.
