What would Saint Thomas à Kempis say about Facebook and other social media?
Here is a quote from the Twenty-Fourth Chapter of The Imitation of Christ, Avoiding Curious Inquiry About the Lives of Others
The Voice of Christ
MY CHILD, do not be curious. Do not trouble yourself with idle cares. What matters this or that to you? Follow Me. What is it to you if a man is such and such, if another does or says this or that? You will not have to answer for others, but you will have to give an account of yourself. Why, then, do you meddle in their affairs?
Behold, I know all men. I see everything that is done under the sun, and I know how matters stand with each—what is in his mind and what in his heart and the end to which his intention is directed. Commit all things to Me, therefore, and keep yourself in good peace. Let him who is disturbed be as restless as he will. Whatever he has said or done will fall upon himself, for he cannot deceive Me.
Do not be anxious for the shadow of a great name, for the close friendship of many, or for the particular affection of men. These things cause distraction and cast great darkness about the heart. I would willingly speak My word and reveal My secrets to you, if you would watch diligently for My coming and open your heart to Me. Be prudent, then. Watch in prayer, and in all things humble yourself.
