The enemy will never cease to cast into your house, if he possibly can, impurity of every kind.
It is your duty neither to refuse nor neglect to throw out that which is cast in,
for if you are negligent your house will become filled with impurity,
and you will be unable to enter in there.

Therefore whatever the enemy casts in little by little, throw it out little by little,
and your house shall remain pure by the grace of Christ.
(Paradise of the Fathers)
