- How do you know infallibility is true? Unless it’s really general like Love God and your neighbors? The more specific a dogma gets, the more it’s liable to error, b/c humans cannot understand God perfectly.
No, humans cannot completely comprehend God, but for the particular truths He has revealed, He has done so so we could believe them. It is in faith that we believe all He has revealed–we have faith that He would not deceive and that He asks us to believe these things because He loves us and because it is the best for us. Likewise, for that same love, we believe He ensured that that truth will be preserved and handed down for all men of all times.
Likewise, many things God reveals for us to believe may seem unreasonable to us. But that is what faith is all about–to trust God’s wisdom over our own–thus Abraham and Mary received completely unreasonable commands (Abraham: to sacrifice his only son just after God promised to increase his posterity through that son; Mary: to miraculously become pregnant as an unwed teenage where such individuals were cast out of society or even stoned) and both assented in faith because they trusted in God’s love.
Sure, reason can aid in this, but it can’t be the only tool we use–as our own reason is limited and fallen.
If we believe we can’t know the truth God has revealed for us to know, we have no faith in God’s power or wisdom or love.
As for love, God has revealed the truth He has so we know how to love Him and our neighbor to the depths He call us to–the world offers many counterfeit loves, from the superficial to the downright sinful.
- What is the origin of the idea that one should not accept other religions? Is this God’s will?
If you believe in the inspiration of Scripture (a dogma), then God makes it pretty clear there is one true faith. He teaches His people to only worship Him, and the Apostles later do the same and teach us to reject false Gospels.
Since God cannot deceive, and since truth cannot contradict truth (for some reason we can accept this maxim for truth about anything accept God…), anything that contradicts what He has revealed is therefore not true. And anything that deviates from truth should be definition be rejected because it is at odds with God’s love (since the truth He has revealed is for love and because He is truth and He is love).
