Rome (CNN) - More than 200 Catholic bishops, priests and laypeople from around the world gathered in Rome this weekend to begin discussing Catholic teachings on a range of hot-button topics, from contraception and same-sex unions to polygamy and communion for divorced and remarried Catholics.

The issues, which the Vatican places under the heading of “pastoral challenges of the family,” were chosen based on the results of a worldwide survey of Catholics in 2013.

Pope Francis called the meeting, known as a synod, to address modern issues facing families today - a topic that he has made a priority since the beginning of his pontificate.

The Catholic Church, the Pope has said, must make sure “it really is in contact with the homes and the lives of its people and does not become a useless structure out of touch with people.”
