Yes, I think her attitude right now reflects a rebellion against authority, and that’s not a helpful attitude, regardless of whether she ultimately chooses to become Orthodox or stay Catholic. Both the EOC and the CC expect us to obey our authoritative teachers the bishops and the priests. Let’s look at her causes of anger one by one, based on DL82’s post:
“…is very angry with the Church over its stance on birth control, over the judgmental attitudes of people in her parish, and over past abuse by a priest. I can see how she has been hurt so badly that going to Mass in a Latin Rite Catholic Church would not be possible or beneficial right now.”
Regarding ARTIFICIAL birth control (I assume you mean ABC - artificial methods as opposed to periodic or total abstinence), that may work out for her but not necessarily. If she believes in obedience to a spiritual director, if she is ready to obey a priest regardless of whether permission to use ABC is granted or withheld, she will be OK with the Orthodox Church. But if she believes that she as a layperson can do whatever she wants and decide whether to use ABC and sterilization without first asking for and obtaining her Orthodox priest/spiritual director’s permission, then this lady and the EOC are a bad match for each other.
I also think DL82 could help her by engaging her on a discussion regarding her beliefs on ABC. What exactly does she believe and why? Does she believe in total freedom to use ABC, left up to the individual to decide on his/her own, or does she believe in the individual obeying the guidance of a priest/spiritual director on this? How did she arrive to her beliefs? Has she studied the Bible, the writings of the Early Church Fathers, and the 2000-year history of Christianity regarding contraception? Does she know that all Christians, including the Catholic Church, Eastern Orthodox Church, and mainline Protestants (followers of Luther, Calvin; the Church of England) universally condemned ABC before 1930, for nineteen centuries in a row? Does she know that acceptance of ABC is an innovation started with the Church of England in 1930, and gradually adopted by Eastern Orthodoxy after the 1960s?
Regarding judgemental attitudes by other parishioners, and abuse by priests, I think all Churches and denominations have their problems, including the Orthodox and Protestants. No EO Church or any other Christian body can give her a guarantee that she won’t encounter judgemental attitudes by other parishioners and abuse by priests/pastors in their particular Church or denomination.
