You can "subscribe" to an ical feed of the lds.org calendar. That will give you a read-only copy of the calendar within the iPad's default calendar program.
From the lds.org calendar, select "settings" -> "sync". That will take you to the calendar sync page. On that page select "Apple iCal". There you will see a url that will be used to access your calendar. Make note of that URL (if you are doing this from Safari on the iPad, you can select and copy the url).
On the iPad, under settings, select "Mail, Contact, Calendars". On the right side, choose "Add Account...". Then choose "Other". Then "Add Subscribed Calendar". On the pop-up window in the field for "Server", enter or paste the URL from the lds.org calendar, and click "next" at the top of the window. You'll need to provide your LDSAccount credentials, and probably want to rename the calendar something like "Stake Calendar". Then click done.
Now from the calendar app, under the "Calendars" menu button (top left) you should see your lds.org calendar (whatever you called it) available to be displayed. You can toggle on or off whether you want those items listed.
