Pope Francis wears a crown of flowers, gifted to him by indigenous Mexicans, as he arrives to the airport in Tuxtla Gutierrez, Mexico, Monday, Feb. 15, 2016. Francis is celebrating Mexico's Indians on Monday with a visit to Chiapas state, a center of indigenous culture, where he will preside over a Mass in three native languages thanks to a new Vatican decree approving their use in liturgy. The visit is also aimed at boosting the faith in the least Catholic state in Mexico. (AP Photo/Gregorio Borgia)
