* the #SSPX
* the modern Roman church of synodalism.
Best thing to do as lay people is to pray for clarity and resolution in the Church, and to live out the Faith of the saints and the perennial teachings of the Church.
πΏ Pray the Rosary.
βοΈ Read the Saints.
π Read the catechisms of Baltimore, Pius X, Trent, etc.
π Read the Bible.
πππ Pray, pray, pray
