Through the “Share” option you can send the text to your friends via e-mail, text message, or by any other means available on your device.
Facebook – a different story. If you have a Facebook app on your phone, you’ll get an option to share on Facebook via the “Share” option, but most likely – that will not work. I found out that it is due to some limitations of the Facebook app and although they’ve promised to fix that, who knows if and when it would be done.
Thus, use the “Post on FB” button to directly post St Theophan’s daily contemplation to your Facebook wall!
