The theme seems to ignore the setting under General → Reading to only display summaries. What you can do is add a “more tag” to the place where you want your excerpt to end. For example:
Four score and seven years ago our fathers brought forth on this continent,
a new nation, conceived in Liberty, and dedicated to the proposition
that all men are created equal.
<!--more-->
Now we are engaged in a great civil war, testing whether that nation, or any
nation so conceived and so dedicated, can long endure. We are met on a great
battle-field of that war. We have come to dedicate a portion of that field,
as a final resting place for those who here gave their lives that that nation
might live. It is altogether fitting and proper that we should do this.
In this example, only the first paragraph will be displayed on the blog page. The more
tag itself will not be displayed because it’s in the form of an HTML comment. You also want to make sure you are editing your post using the Text editor instead of the Visual editor.

Yeah, but that’s a pain to make sure and remember each time and/or go back and add it to all past posts. I did find this plugin that’s helpful when the theme doesn’t do it, though: https://wordpress.org/plugins/activate-update-services/
