Click Events in the navigation menu (at the top of the page).
Click Create Event.
Complete the form that appears. Some sections (Summary, Description, etc.) can be enabled or disabled by clicking the switch on the right of that section.
If you decide to add a description, you will see a toolbar appear above your text. Select any text and click one of the buttons to make text bold, italic, underlined. You can also create a header (slightly larger text), and a bulleted list.
If you'd like to add an image to your content, click Add Image on the toolbar. This opens the image picker, which is pre-populated with stock images free for you to use. Alternatively, if you'd like to use an image you already have on your computer, click Upload Image. Once you've chosen the image, click Use this image.
Click Create. The event (or events, if it's a recurring event) will be created and your church members will see a post on their timeline.
