The following website was unreliable resources. They claim to know basic Catholic belief but they don’t. I know there are more but these are the ones I just pick up by Googling them.

If you seek to find the Catholic Truths use only Catholic Resources.
You would not go ask a Catholic about Jewish belief or ask a Catholic for Greek Orthodox.
You want to know what the Catholic profess read the Catechism of the Catholic Church, used Catholic resources online, mainly Catholic Apologetics sites, as well, as ewtn.org
newadvent.org is also reliable.
