I often read the Bible two or three times a week. I am reading the Bible straight through (I did this once before but it was many years ago so time to do it again) so I will either start reading where I left off, or else I will catch up on the daily Mass readings because some weekdays I am late for Mass due to having to drive to find one, or due to work or other daily stuff, and miss the Liturgy of the Word,
I don’t just use the Psalms exclusively. That would be boring, and unless one reads the rest of the Bible, one is not going to be viewing the Psalms with great understanding and in context.
In general, I find many Scriptural devotions to be a very fragmented approach to the Bible and while useful for meditation, devotion etc such fragmented readings do not give you a good sense of everything that’s in there.
I sometimes also pray Scriptural rosary or do some other devotion like Stations of the Cross using Scripture.
I think more Catholics would benefit by just reading the Bible straight on through, including the boring parts like geneologies and Leviticus that the “Bible study” courses like Ascension Presents often just skip. Reading the boring parts causes you to consider why they are included and what was their purpose and why was this very important to the audience when it was written. All good questions.
