Encyclicals
The pope teaches the Church in matters of faith and morals with a charism of infallibility, so long as he teaches "ex cathedra," that is, so long as he is teaching in his official capacity as the head of the Church. Infallibility aside, the pope teaches the Church by giving addresses to audiences in the Vatican City, by writing encylicals, apostolic constitutions, and motu proprios.
The church teaches that marriage lasts throughout a lifetime because when two people marry in the church, they are making a pact with God as well. When an agreement is made with God, the agreement can never be broken.
