Here are a few comments on your girlfriend’s outlook concerning Catholics.
So is the Bible.
…(premarital sex, living together before marriage…)
This is the sin of fornication and is expressly denounced in Scripture. Historically it has been universally considered a sin according to Catholics, Protestants and Jews. In recent times certain Christians have tried to rationalize this sinful behavior, as people tend to do with the sins they want to indulge in (for example, saying things like, “Living together is not really the sin of fornication as long as it is a ‘meaningful relationship’”). In such cases, people act as if they are their own popes, providing their own official interpretations of Scripture and living accordingly.
…have to go to church)
Jesus went to church, in that he regularly went to the Temple and synagogues. Likewise, he founded a Church. If Jesus went to church and founded a Church, then why should someone have an issue with Catholics saying that a Christian has to go to church?
Now she has begun reading Anti-Catholic propaganda.
If she has any specific criticisms (beyond what was stated in your OP), then, by all means, post them in this forum.
Recently we had a talk about religion that ended in a fight (never raising voices but I walked out when she called belief in The Eucharist “stupid”).
I’m not sure what she meant by “belief”, but if this concerns the Real Presence then it sounds like she is out-of-touch with her own Lutheran theology. Lutherans have always believed in the Real Presence in the Eucharist. Historically they have explained this as consubstantiation (as opposed to the Catholic doctrine of transubstantiation). A number of modern day Lutheran theologians have elected to simply state that the Eucharist is the Real Presence of Christ, but think that people should avoid explaining the way in which this happens with any specific terminology (such as consubstantiation or transubstantiation) because it is a divine mystery.
The way I see it, although there are differences in how Catholics and Lutherans view the Eucharist, these differences are not all that great, and so I fail to see how your girlfriend could denounce Catholic belief as “stupid.” After all, what makes Catholic belief down-right “stupid” and Lutheran belief acceptable? For example, whereas I do not believe in consubstantiation, I don’t say that belief in consubstantiation is “stupid.”
This morning she posted a link to an Anti-Catholic site on her facebook page.
Does she mention on her FB page that she has a Catholic boyfriend?
She claims that because I have never been to Europe my eyes are not opened to the truth (her parents were wealthy mine were not, spending summers overseas was not an option).
Well, I am from the U.S. and I have been to Europe, and I am still Catholic. Furthermore, how does she explain the fact that there are so many European Catholics? Where does she think Vatican City is??? And maybe you should remind her that Germany, the European birthplace of the Protestant Reformation, is also the birthplace of our current pope.
I love this woman with all of my heart, but it seems that she is becoming a bigot against my faith. She refuses to listen to me or read any Catholic resources. I pray for an answer every day. Please help.
I will pray for her as well. I am sorry to hear that she refuses to listen to you or read any Catholic resources. Lack of communication in any relationship is always detrimental, and few relationships survive as a result.
