In order to go on along the "journey of human maturity", the Church, recalled the Pope, "teaches us to respect and promote the wonderful reality of the indissoluble marriage of man and woman, which in addition is the origin of the family. For this reason, recognising and helping this institution is one of the most important services one can render today to the common good and to the true development of men and society, as well as the best guarantee of the dignity, equality and true freedom of human beings". Then, Benedict XVI invited all Christians "to cooperate with all the men of good will, so that, by joining forces and with a legitimate plurality of initiatives, they may help promote the true good of the family in today’s society". "The Christian family a father, a mother and their children is called went on the Pope to pursue the established goals, not as something that is imposed from outside, but as a gift of the grace of the sacrament of marriage inspired in the bride and groom". The presence of the Spirit between the bride and groom will "help them not to lose sight of the source and dimension of their love and their mutual self-donation, as well as cooperate with it to reverberate and incarnate it in all the dimensions of their life". "This concluded the Pope is the message of hope that I want to send from Valencia to all the families of the world".
