We can use this as a fake news report.
The headline is wrong. The report saysāHalf of Catholics in the United States (50%) correctly answer a question about official church teachings on transubstantiationā¦ā The headline is probably misreading that 1/3 of all respondents get that question right.
The question on the Eucharist is wrong as well.
Which is the Catholic teaching about bread and wine in Communion?
They become actual body and blood of Christ
they are symbols of the body and blood of Christ
Both of these are correct answers, so everyone actually gave a correct answer. A modifier like ājustā or āmereā for symbols would make the 2nd answer wrong, and the text of the report includes that. But the question asked did not include it. That also explains why 2/3 of all respondents gave the supposedly wrong answer; a little knowledge of sacramental theology would tell you that sacraments are
signs that
signify, which most people understand as synonymous with
symbol.
100% of respondents gave a correct answer, because both choices were correct.
[This was discussed in detail in the late medieval period, with distinctions made for
sacramentum, the sign,
res, the thing signified,
res et sacramentum, the combination, the
res tantum, and more.]
[As the Catechism says āthe
sacraments are perceptible
signs (words and actions) accessible to our human nature. By the action of Christ and the power of the Holy Spirit they make present efficaciously the grace that they signify.ā The grace that is made present is the grace that the signs symbolize. If they are not symbols, there is no grace to make present.]
