God Bless you Caroline,
Your best bet is to live the love & sacrifice that Jesus taught us. If they see the joy & positive example you present as a Catholic, they will eventually want what you have!
Learn your Faith well, so you can defend the Truth when the opportunity arises.
Most Protestants don’t know the Truth of the Catholic Faith because we Catholics often do not know it as well as we should. They have been told false things like Catholics worship Mary & pray to statues, etc, etc…
They often have been taught false interpretations of Sacred Scripture as well, like Once Saved, Always Saved, that can lead them astray.
If we do not teach them the Truth, who will?
**Read Sacred Scripture daily (EWTN has the daily Mass readings from Sacred Scripture & a homily here; ewtn.com/audiovideo/index.asp#VOD) as well as daily Mass 3 times every day online video. **
You can search the Catechism of the Catholic Faith here; scborromeo.org/ccc.htm to answer questions. Catholic Answers & many other online sources like EWTN also have resources to answer questions!
Sancta Maria, Mater Dei, Ora Pro Nobis Peccatoribus!
