Those who have paid attention to this Pope and what he has done in the past are not at all surprised by this pronouncement. There will be more such pronouncements to be sure.
He sounds like a reasonable, relatively orthodox man. Far more surprising would be for him to say such violent abominations are okay. If there is one thing that the Roman Catholic church does very well, it’s the explicit recognition of the proper, sanctified use of nature, including sex and life issues.
