They may be but from my seat looking in they sure have babies out of wedlock. Just sayin.
Many people conceive children out of wedlock, regardless of what their stated principles on the matter are. People can be faithful and foolish at the same time. Catholics have long been having babies out of wedlock. That doesn’t mean they are not Catholic. But it can mean they are more committed to actually giving birth to the children they conceive out of wedlock than some other people are, and getting married and raising the children. A number of people in my extended family did that. They rose to the occasion and ultimately became heads of good Catholic families.
I recently talked to someone in Hispanic ministry about that. She said that the Hispanics were naturally pro-life, but were often very poorly catechized. Her co-worker in ministry, who is from Mexico, also talked about how there were villages in Mexico who saw a priest only once every six months. The priest would come to town to baptize the new babies, say Mass and hear confessions. Ever since the Mexican slaughter of priests decades ago, there have not been enough priests to make more frequent trips to those villages. Hispanic ministry in the US often has to focus on the most basic kerygma because more advanced doctrine is simply beyond the understanding of the people because they never were catechized growing up at home.
