The Lord God will judge you severely, most severely, if you allow your children to engage in media harmful to their Faith or Morals. For example, the tv, internet, friends, and etc...
You are just as guilty as them, and share in their crimes, if you allow them un restricted use of such media.
There are many OT movies that are excellent, and a few NT ones. However, due to the immorality in some, you must pre censor them, before allowing them to see them. This is not a hard task. Just buy some used ones for example at ebay or amazon or anywhere. Copy them onto your computer, and cover some scenes, or erase them, as need be, to as not to injure their Faith and Morals.
A few ones to get are Jeremiah, Moses, Abraham, David, Solomon, The Passion of the Christ, St. Anthony, St. Patrick, Black Robe, and more to be added to this list later on.
Put first the Kingdom of God, and all else will be added to you. Forbid them to use the internet without your immediate supervision, and then only to go to safe sites. Put filters on their computers as well. God will not be mocked. Neglect not these holy admonitions, lest you sin by omission. Put the Faith first. All else is secondly done. Much more to be added, as time goes on, and is prudent to do so!
