The errors of "brothers and sisters of Jesus" is discussed earlier in this thread, I believe with a link provided. I can look for it - or others - again, if you wish. But I'll focus on another aspect:
Either these passages that you say mean Mary gave birth after Jesus are newly discovered or newly interpreted into something no theologian of the Church - and none of the leaders of the Reformation - saw. Or they were very aware of scripture and held that Mary was ever-virgin.
I think it strains credulity to think these men were unschooled in scripture or interpretation.
No, the scripture never meant Mary gave birth to anyone other than Jesus, the modern innovative exegesis of some notwithstanding.
As for the reformers or any other “church leader”, they are all human so I will put my faith in Gods’ word.
As you are human, you are putting your faith in your interpretation.
For me it is clear that without the Church, we have have no authority but ourselves. Remove the Church and you remove all authority but yourself. And your authority is no greater than any one else's.
This leaves us at an impasse, each his own authority, each claiming truth - which is impossible as this case illustrates. And this shows the wisdom of Our Saviour in establishing His Church as the pillar and foundation of truth.
thank you very much for your courteous reply. God bless...
I believe in Gods’ authority, hence his word in the Bible.
You seem to choose the word of humans over God, that is your choice.
