ja4, you have been given multiple examples of Sacred Tradition, and have defined it as “speculations of men”. It is odd that you accept some of the Sacred Traditions, such as the canon of scripture, the hypostatic union, the Apostles Creed, and the Trinity, but reject others.
However, since you have said that you have to pick and choose your doctrines, I suppose this is why.
Now, given that Sacred Tradition is part of the Divine Deposit of Faith that was handed on to us from Jesus Through the Apostles, lets explore your questions:
Was not eating meat on Fridays during lent, Stations of the cross and saying the rosary SACRED TRADITIONS?
Let’s engage some common sense, shall we? Lent is part of the Liturgical calendar that did not exist in apostolic times, so it cannot be part of the Sacred Tradition.
Stations of the Cross did not emerge until the dark ages when most of the faithful could not read, and needed visual cues to follow the gospel message. Therefore it does not qualify.
Saying the Rosary is a private devotion, none of which are binding on the faithful, and therefore it does not qualify.
