The Mexican bishops' conference welcomed the changes, saying in a March 29 statement that with the reforms, "Mexico incorporates the highest levels of respect and promotion of human rights."
Critics of the measures, including some non-Catholic congregations, questioned why amendments were necessary and warned the changes would allow for the religious education and religious groups owning TV and radio stations -- two Catholic Church priorities in Mexico.
"In Mexico, there's religious freedom. What's limited is priests' political expressions," Sen. Pablo Gomez wrote in the newspaper Milenio. Gomez opposed changing Article 24.
The constitutional changes now must be approved by a majority of Mexico's 31 state governments.
