Purgatory (1 Cor 3:15).
Eucharist (1 Cor 11:23-27).
Communion of Saints (Rom 12:12-20).
The Mass and the necessity to attend (Heb 10:25-31).
The Sacrament of Confession (Heb 13:17).
The Sacrament of Holy Orders (1 Tim 4:14).
The Sacrament of Baptism (Titus 3:5).
Justification and salvation by faith and works (Rom 2:1-13).
Etc. etc.
