In essence, vaccination says to your most vital immunological defenses, “I have no need of you” — despite their critical role in a proper immunological response and in filtering poisons (such as vaccine ingredients). Practically speaking, when vaccination is performed, the organs and protections that it bypasses are removed, as their uses in that occasion are nullified.
Unsure as to whether to vaccinate? Research vaccination (not just the propaganda of the pro-vaccine side), and you will see that the process stands condemned by the fatal fruit it continually reaps.
Is ignorance of the sin of vaccination morally excusable? That is, is it not sinful to vaccinate someone or be vaccinated if one does not know that it violates God’s law, such as the Sixth Commandment?
Vaccination both injures and kills – and on a large scale at that. And so, as the Catechism describes, it is not, as its propagandists assert, a “lawful and necessary means of preservation of life,” or “a sober use of … physic [medicine].” On the contrary, it is “striking, wounding,” and even the “taking away the life of ourselves, or of others.”
The crux of the vaccine debate is morality, or ethics. That is, “ought we to vaccinate?” This must be decided by Scripture, as Jesus is King of kings, and has all authority in Heaven and on Earth. Therefore, He must be obeyed in all areas of life; Scripture equips for every good work (2 Timothy 3:16, 17).
