This is by no means a comprehensive list. David Lim is just filing some thoughts as answers to the view of Roman Catholics in infallibility of the Catholic Church. Infallibility applies to the Church's teaching on faith and morals, which are in turn based on revelation. The Pope John Paul II preached God the Mother and affirms the Virgin Mary. RCs believes in oral and written tradition contradicting scriptural teachings.
Scriptures makes no distinction between teachings for daily living, faith and moral.
They are all revelation of the same Spirit for the welfare of the body of Christ. Yet practices of RCC have not been blameless. The organisation sinned so much and so obvious that she had to apologise to the World of non-believers of her crimes. RCs use the argument that christians ask other christians to pray for them as well. Scriptures do not teach that the departed are closer to Christ than living believers.
