The entire article bothers me because....

Everything 'Christian' is explained by European and Roman Catholic history. A entire section of Christianity is left aside.

As the Bible does discuss 'marriage' does it really go back as far as the Greeks? Why did the article not discuss the actual reasons for the practice in Mesopotamia? Point being that everything did not begin with Europeans.

Personally, I believe that we all come from one origin and as we spread, our ideas did the same. Our reason for marriage probably changed as well, depending on the peoples. The term Christianity was coined at a certain point but the Old Testament/Oral traditions predated it. As people branched out and their relationships with God developed...many different religions/traditions came about.

In my opinion, Marriage was most likely of religious origin as it is found in most religions and established to serve multiple purposes. But with time comes change...

However, to me, this article is too limited.
