Activate Comments for static page

Hello, How can I activate the comments for a static page in Catch Box Pro? I remember that there was a comment function in the free Catch Box Theme which I miss now for a static page. But I want it only on one page, not for the rest of my website. If it is not possible and I have to create a blog in order to show up comments, how can I make a Blog ressemble a static page? I want to remove author and date of the blog and show up all of the content on one page without redirection (remove "read on here"). Thank you for answering, Sarah
