[18] At the seventh conference in 1977, Las Hermanas decided they would develop a strategy to promote women's concerns at the Second National Encuentro of Hispanic Catholics which was happening later that year.
[11] During the testimony, Sisters Beatriz Diaz-Taveras, Maria Teresa Garza, Ada María Isasi-Díaz and Carmen Villegas testified about Hispanic women's oppression in the Church, in their families and in broader society.
When conference planners did not allow the vote to go through, Las Hermanas, including Isasi-Diaz and Tarango, protested outside by praying the rosary and refusing to go in.
