@adamp: Thank you for using Clean Journal. Well this can be done in two ways. Either use custom CSS to hide the content from home page, or use the static page.
1. Using Custom CSS: Go to Dashbaord=> Appearance=> Customize=> Theme Options=> Custom CSS box and add the following CSS:
.home #content {
display: none;
}
2. Static Page: Go to Dashbaord=> Appearance=> Customize=> Static Front Page and select A Static Page in Front page displays option and select the Page you want to display on the homepage, and Blog page to to display posts.
Using Static page will display content of the page selected.
