More than 1 million copies of the English voter guide were requested for distribution, many in swing states, she said, and the association began receiving requests for a Spanish version as well.
McGuire sees the Spanish voter guide as an opportunity to reach an important demographic in the presidential election.
She explained that "the majority of Spanish speakers in this country are Catholic and deserve to know how the candidates measure up."
The current admiration has been "deceptive" about the impact that its policies will have on religious freedom in America, she said.
"It's hard for English speakers to navigate it all," she observed, let alone those for whom English is a second language.
"I truly believe that Hispanic Catholics are the future in many ways of the Church in America," McGuire said, pointing to the growing Latino population within the Church.
Therefore, she said, it is "hugely important" for these Catholics to understand the threats facing the Church in this country.
The voter guide is now available in both English and Spanish on the Catholic Association's website and has attracted significant media attention.
While the Catholic Church "does not tell people how to vote," McGuire said, it is important for the faithful to maintain a well-formed conscience.
She encouraged voters to look beyond jobs and the economy to consider "what is right and wrong on a fundamental level" and how each candidate will respond to these basic issues.
"I think that message will resonate with Hispanic Catholics," she said.
