“Even before the (Second) Vatican Council, the conviction of the Church was that lay involvement in certain spheres of life, particularly political and social, was absolutely indispensable,” Archbishop Paul Gallagher told Catholic News Agecny on Dec. 11.

The importance of the laity “is quite clear even more today,” he said, explaining that without their activity and social and political advocacy, the Church would lose its voice.

“It is absolutely key, crucial, for the future of the Church's engagement with society that laypeople should be prepared to do this, should be courageous in doing it, and should have this great will to bring the voice of Christ now in the political sphere and social sphere, on a local level and an international level,” he said.

“I think they can do a great service to the Church and to the world in this way,” he said, adding that “any form of engagement” is encouraged.

Msgr. Gallagher, Vatican Secretary for Relations with States, spoke before celebrating Mass on the opening night of a Dec. 11-13 conference organized by the Forum of Catholic-inspired NGOs, titled “Promoters of Humanity in a Transforming World.”

The conference, which drew a slew of representatives from various NGOs around the world, including non-Catholics, focused on how Catholic-inspired organizations can help safeguard core values such as family and religious freedom, and ensure the that a proper integral human development is achieved in the context of a rapidly changing global society.

In his speech for the conference, Gallagher said the Holy See and Catholic-inspired NGOs can work together to achieve “the ideal of human fraternity and a means for its greater realization.”

He stressed that the Holy See isn't “controlling” the forum, but that rather, the members and leaders of the NGOs are the real protagonists, since they bring “real life experiences and expertise” to the table through their work.

Among those “protagonists” present for the conference was Helen Alvare, a professor of family law, law and religion, and property law at Antonin Scalia Law School, George Mason University. She is also the cofounder of the “Women Speak for Themselves” organization, the president of “Reconnect Media” non-profit communications group, and an adviser to the U.S. Conference of Catholic Bishops.

In comments to CNA, Alvare also stressed the importance of the role of laity, specifically women and the poor, in advocating key issues in the Church, especially in regards to the family.

Through the organizations she is involved with, Alvare focuses on giving voice to people on the grassroots level and empowering them to have a greater role in the push for both religious freedom and the family values lost in the sexual revolution. The hope is to show that questions on sexuality “cannot be separated from issues about economic well-being and poverty and human happiness.”

Pope Francis has been a leading voice advocating for women and the poor, Alvare said. However, while the Pope has set “a wonderful tone” on these issues, she believes that “one of the signs of the times is that it cannot come from top down in the Church.”

“No matter how lovely a tone Pope Francis sets on empowering women and the poor, when the subject matter turns to sex, marriage and parenting, the powers that be don't want to hear from him or the Church in any level,” she said.

Rather, the argument needs to come from those who have supposedly been empowered by the sexual revolution – laity, and especially lay women.

When the Church hierarchy joins forces with laity and religious on the ground, they can have a powerful effect, Alvare said, and this includes reaching the people taken in by the agenda of the sexual revolution.

Speaking of the partnership the Holy See can have with NGOs and the people who run them, Gallagher in his speech highlighted several key areas of collaboration, the first being to advance the 2030 sustainable development goals, which Pope Francis has called “an important sign of hope” and which in large part are aimed at ending poverty, protecting the environment, and promoting education.

He also pointed to the issues of forced migration and displacement resulting in “unprecedented population shifts,” giving specific mention to the 2018 U.N. global compacts on migration and refugees.

Other major areas of concern, he said, are climate change and the promotion of an integral human ecology; the freedom of thought, conscience and religion, which includes concern for religious discrimination and persecution; and freedom of expression, as well as the freedom to convert.

While the global landscape in light of these issues might seem “immense and complex,” Gallagher said it is also promising, because the efforts that appear to be small are capable of “developing and achieving ends for the benefit of the common good of all.”

In a brief Q&A after his talk, Gallagher encouraged members of NGOs to be active and involved in the debate on relevant issues in their competence, keeping the papal representatives in the loop on the discussion and seeking advice or input from the Holy See when needed.

“Part of the thing about autonomy, is one shouldn't be waiting for instructions,” he said. “It's about working together, its about collaborative ministry together,” he said, adding that it's not about “a voice coming from on high saying, 'Do a,b,c'.”

Responding to a question on his advice for Catholic doctors and medical personnel who work with Catholic-inspired medical organizations, Gallagher said the most important traits needed today are “great courage and sacrifice.”

Part of this courage also means exercising the right to follow their conscience. “We expect you to assert the rights of your conscience and that of your more vulnerable colleagues,” he said, adding that the role of the conscience for those working in the medical field right now “is absolutely fundamental.”
