As pointed out by others, the Church does not have a negative position on firearms ownership.
As to the notion of right of ownership…This is indeed enshrined in the Constitution, but in a way that is generally not well presented…
The purpose of the amendment to right to keep and bear arms is the need for a “Well regulated militia”. At the time, the nation feared (with good cause) a standing professional army. The government preferred to depend on the states to supply soldiers from their militias for national use.
This of course has changed considerably from ca 1800 to ca 2000, yet the fundamental idea of the right of the individual to keep and bear arms remains firmly implanted in the national psyche…and, I believe, with good cause.
That said, it remains a fact that the amendment is NOT to ensure the rights of the citizenry to revolt - or to keep the government in fear of an armed citizenry - It is to provide a “Well Regulated Militia…” and as such, the Government is perfectly within it’s constitutional rights to “regulate” said “militia”.
Measures such as gun registration, waiting periods, training classes, etc easily fall into this category of regulating the militia. The government would even be within it’s rights to require that all gun owners meet regularly for basic training in military tactics etc. I’m not saying they ever would, but they certainly DID back in the 1700’s and early 1800’s.
Gun owners my not like it, but there it is…If you want to use the amendment to keep your firearms, then you must embrace and accept the entire amendment.
As for gun ownership for persona protection etc…guns exist. Nothing changes that. From there the individual must recognize and accept the risks and responsibilities that go along with the decision to keep (or not) a gun in their house or on their person.
Peace
