"Today people want to love, but it is a love without truth, which means, on the one hand, love without duration; and on the other, love without the ability to transmit to children born of that love a sense of life; finally, love without public impact, because the truth is what unites us with others," he commented.
"Therefore, to speak of the truth of love is to remember that there is hope for love, that it can be long-lasting and fruitful."
Granados said that proclaiming the "truth of love" would have an impact on the pastoral care of families.
"For example, the Lord's mercy is united with the truth, because it is not a mercy that is limited to tolerating our misery and fragility, but a mercy that regenerates us so that we can live up to our vocation to love," he noted.
"And it is also a truth that reminds us that our love is generative, capable of transmitting the life that comes from the Creator."
He underlined that the initiative had a pastoral dimension: "to form families in the love of Christ."
He continued: "The challenges are many: educating children to love, strengthening the conjugal union, especially in the first years of marriage, working for a society that puts the family at the center, protecting the family from ideologies that deny the unitive and procreative meanings of the human body, and even the sexual difference itself."
The priest said that the Veritas Amoris Project would hold a congress for families each year in a different country, preparing "formators of family ministry."
The project is holding a seminar for professors in Rome on Feb. 2-4, entitled "Pathways of Truth."
"There will also be an academic meeting every year in Rome, to deepen the project, which we have collected in 12 programmatic theses," Granados said.
The 12 theses expressing the project's vision include statements such as "To speak of the truth of love, one needs to establish the primacy of God as Creator"; "To speak of the truth of love in today's emotivist climate requires a reflection on the affections"; and "The perspective of the truth of love has great social potential."

Granados said: "We are also launching the 'Veritas Amoris Review,' currently online, as well as a publication project, featuring both original works and translations."
"We hope little by little to be able to offer courses -- online or face-to-face -- on different topics around marriage, the family, and the vision of God and man that derives from there."
He said that the project was a sponsor of a three-day symposium in January, "Towards the future with St. John Paul II," marking the 100th anniversary of the Polish pope's birth.
Other members of the project's scientific council include Fr. José Noriega, a teacher of fundamental moral theology at St. John Vianney Seminary in Denver, Colorado; Sr. Alexandra Diriart; Fr. Juan José Pérez-Soba; Monika Grygiel; and Stephan Kampowski, a professor of philosophical anthropology at the Pontifical John Paul II Theological Institute for Marriage and Family Sciences in Rome.
Kampowski told CNA: "The initiative is born out of the need to spread a vision of the family that we all received in our study together."
"We believe this vision to be fruitful for the teaching on love and on family, and for the pastoral care of families."
