A Roman Catholic bishop claims gay marriage is responsible for “the destruction of the family” and “the significant increase in children with severe disturbances of personality.”

Bishop Casimiro Lopez Llorente of the Roman Catholic Diocese of Segorbe-Castellon denounced marriage equality, legal in Spain since 2005, in his final pastoral letter of the year, titled The Good News of Marriage and the Family.

The effects of same-sex marriage, the bishop wrote, are “weakening the lasting love between spouses, maternal and paternal love, familial love, the significant increase in children with severe disturbances of personality and the development of a climate that often ends in violence.”

Lopez also doubted that the church must adapt to changing times, saying that such progress is responsible for the growing number of broken families and adds to the suffering of children, Spanish news agency EFE reported.
