Right. So I dug through that and the related sub trees of linked articles. Here’s what I found:

• The claims of a link between George Soros and Christianity Today (CT) are given in the article as Ed Stetzer, editor of CT’s “The Exchange”, posting an article on immigration reform by Matthew Soerens.
• The article existed on The Exchange website in the past. archive link
• The Exchange website has since been replaced. The referenced immigration reform article by Matthew Soerens was not preserved.

Here’s the original claim by u/DigitSoldier

Christianity Today is a Soros funded propaganda rag.

I don’t see support for this claim. One person running a new website under the CT umbrella ran one article one time, and that article is already gone.

Full disclosure: I have no interest in CT, I don’t read it, and I have no reason to recommend it to anyone.
