“It should be noted that condom use cannot provide absolute protection against HIV. The surest way to avoid transmission of HIV is to abstain from sexual intercourse or to be in a long-term mutually monogamous relationship with a partner who has been tested and you know is uninfected.”

In the very editorial criticizing the statements of Benedict XIV, The New York Times ends up by recognizing that he is right. Speaking about condom effectiveness to prevent AIDS, after mentioning the CDC and the Cochrane Collaboration organization, the Times warns: “However, both groups warned that condom use cannot provide absolute protection. (...) The best way to avoid transmission of the virus is to abstain from sexual intercourse or have a long-term mutually monogamous relationship with an uninfected person.”
