Do you hold to the Biblical prohibition against eating shellfish?
Do you hold to the Ten Commandments?
Probably "no" and "yes," because the former is an example of the provisional, ceremonial Levitical laws, while the latter is an example of the eternal, moral Mosaic law.
Similarly, there are different kinds of law in Christ's Church, "the pillar and foundation of truth."
To know what they are, we must "listen to the church," because Christ gave His Church the power of "binding and loosing." (Matthew 16:19, 18:18)
Some law is dogmatic, infallible Teaching, and some law, like parts of canon law, governs the operation of the Church, and is comparable to the civil Levitical law. Similarly, the Church is not infallible in the realm of the natural sciences, but only when invoking Her Authority regarding matters of faith and morals.
My Lord and Savior, Jesus Christ, took His blood and spread it upon the Mercy Seat in Heaven, covering the law of sin and death. The Levitical laws are no longer my concern. The ritual laws are not my concern. My concern is allowing God as the indwelling Holy Spirit to be God in me. Try it, you’ll like it! Stop playing the game of the Nicolaitans.
Do you still get hungry and thirsty? Do Catholics still die?
