 The use of condoms to prevent STD transmission is not specifically addressed by Catholic doctrine , and is currently a topic of debate among theologians and high @-@ ranking Catholic authorities . A few , such as Belgian Cardinal <unk> <unk> , believe the Catholic Church should actively support condoms used to prevent disease , especially serious diseases such as AIDS . However , the majority view — including all statements from the Vatican — is that condom @-@ promotion programs encourage promiscuity , thereby actually increasing STD transmission . This view was most recently reiterated in 2009 by Pope Benedict XVI .
