What are we to make of a theologian who says this?

“But in Europe, in the nineteenth century, the two models were joined by a third, socialism, which quickly split into two different branches, one totalitarian and the other democratic. Democratic socialism managed to fit within the two existing models as a welcome counterweight to the radical liberal positions, which it developed and corrected. It also managed to appeal to various denominations. In England it became the political party of the Catholics, who had never felt at home among either the Protestant conservatives or the liberals. In Wilhelmine Germany, too, Catholic groups felt closer to democratic socialism than to the rigidly Prussian and Protestant conservative forces. In many respects, democratic socialism was and is close to Catholic social doctrine and has in any case made a remarkable contribution to the formation of a social consciousness.”
