Youāll hear about as many definitions as there are persons, but as somebody who feels that she is drawn to many traditional practices, I believe a traditional Catholic, as opposed to a 'just plain Catholic" or a 'modern Catholic ('plain and modern not being the same), is a person who believes in the āthree legged stoolā of Sacred Scripture, big-T Tradition, and the Magisterium, who while being perfectly content and appreciative of the O.F. (ordinary form or āvernacularā Mass) yet appreciates the E.F. (extraordinary or Latin Mass) and its gifts as well; who appreciates little-T traditions which existed for centuries yet have been neglected over the last 40-50 years, things such as women with headcoverings, devotions to the Sacred Heart, things like ember and rogation days, the traditions of the liturgical year (things like knowing that the month of December is dedicated to the Immaculate Conception and the month of January to the Childhood and Holy Name of Jesus), Saturdays dedicated to the Virgin, the age-old tradition (with indult in the U.S.) for Friday abstinence from meat, First Fridays and First Saturdays, an appreciation of things like chant, family rosaries, etc.
Now with the probable exception of headcoverings, I am sure that both ājust plain Catholicsā and progressive modern Catholics are aware of and even practice or have practiced some of the above. So Iām not saying that those who appreciate tradition are somehow incredibly different or better, or are informed while others are ignorant. Not at all.
I am saying that it will most likely be those who either self-identify as traditional or who find themselves appreciating a majority of the things above and other practices which were once common in our grandparents day as devotions and traditions in the Church who will be practicing some or all of the above. And that the ājust plainā Catholic will most likely practice only that common to his or her family culture (i.e., the Catholic of Italian heritage will probably celebrate the Feast of St. Anthony on June 13, but be less likely to celebrate ember or rogation days, while the modern Catholic of Italian heritage may not think of St. Anthony at all, or will find the āold fashioned processionsā quaint and even problematic, ārigidā, lacking relevance in the modern diverse world. Again, of course, these are broad generalizations and obviously you can find people who identify as one of the three groups above who go against ātypeā.
