Welcome to this week’s “Throwback Thursday” installment. Today, we’re going to revisit a post that was originally published back on October 24th, 2017 and has been revised.
Sister of Mercy: From Serving God to Knowing Him
By Wilma Sullivan
Emerald House Group, 1997, 80 pages

In this short book, former nun, Wilma Sullivan, testifies of her journey from being a Roman Catholic nun to salvation by God’s grace alone, through faith alone, in Jesus Christ alone.
Sullivan was born into a Catholic family and educated by the Sisters of Mercy at St. Agnes Catholic Grammar School in Towanda, Pennsylvania up until the sixth grade. The dedication of the nuns made a huge impression on Sullivan. Being an athletic girl, she chose to attend public schools from seventh through twelfth grades because of their superior sports programs and facilities, but continued with her CCD (Confraternity of Christian Doctrine) religious classes for Catholic children attending public schools. Sullivan desired to become a nun following high school, but fulfilled her father’s wish that she first go to college.
After graduating from a two-year college, Sullivan entered a Sisters of Mercy convent in 1967. Shortly afterwards, she was assigned to teach a second-grade class at a Catholic grammar school. The Second Vatican Council (1962-1965) brought many changes into the church including changes in religious orders. Nuns were given greater independence. Sullivan was disillusioned with what she saw as the disintegration of community life in her religious order and left the convent in 1971. But she remained loyal to the Catholic religion and volunteered for various assignments at two Catholic parishes.
During a hospital stay, Sullivan struck up a friendship with another patient, a born-again Christian. The two often discussed spiritual matters. Sullivan bought a Bible (her first) and attended weekly services at both the Catholic church and the Baptist church of her hospital friend. She eventually understood that salvation is by God’s grace alone, through faith alone, in Jesus Christ alone and accepted Christ as her Savior. After several months, Sullivan found that she could no longer continue to attend the Catholic church services because so many of the beliefs and practices were contrary to God’s Word, including the RCC’s false gospel of salvation by sacramentalism and merit.
For many years, Sullivan traveled across the country speaking to women’s groups about her journey from legalistic, institutional religion to a relationship with Jesus Christ.
I enjoyed this short book quite a bit and read through it in only a couple of sittings. I was also taught by the Sisters of Mercy in Catholic grammar school. I praise the Lord that Sullivan accepted Jesus Christ as her Savior and came out of Catholic legalism. Rome-friendly, ecumenical evangelical Judases don’t know what to do with a testimony like Wilma Sullivan’s. “If” she is right, they are terribly wrong, so they close their eyes and plug their ears.
