First, of course, we do have messages from our Apostles, in the New Testament. So, are these getting the most attention, then? Or are people getting into other things from claimed Purgatory people or whatever. Are voices "back from the dead" getting more attention than God's word???? How well do you know God's word, compared to how well you know other things?
For just one example, do you know Jesus prayed for us to be loved by our Father the way our Father loves Jesus? John 17:22-26
Has this gotten your attention? Or are other things keeping your attention elsewhere?
I think divine revelation scripture and apostolic tradition shows us there is a purgatory.
How about the New Testament? Do the Apostles in their New Testament writings give this tradition in clear terms?
I notice how Hebrews 12:4-14 says God corrects His children, and the result of God's correction is that we share with Him in His own holiness in His love's "peaceable fruit of righteousness". Does this get at least as much attention as Purgatory, in Catholic tradition?
If not, then Purgatory could be a very dangerous thing of procrastination so people do not personally seek how our Father is now able to correct us . . . so better than we can try. If what we are doing does not work, this is because what we get ourselves to do does not work. God's grace is almighty to succeed in us . . . now . . . no procrastinating.
The Jews did and do as well
Are you talking about Jews who do not honor and obey their Messiah Jesus? If you are talking about Jews still in darkness, I would not trust what they are capable of thinking, if they think Jesus is not their Messiah. They are not a source, I would think, of authority for what is Christian belief, if they don't even believe a basic.
So, is God's word getting your attention, most of all? Canon Scripture has so much of what Apostles themselves have given to us. And God's grace does all He means by what He says. He in us does what His word means >
"for it is God who works in you both to will and to do for His good pleasure." (Philippians 2:13)
So, this is a basic of Christianity, how God personally shares with us, having us will and do what He really wants. He is not distant from any of His children.
"And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful." (Colossians 3:15)
So, this is a basic of our calling > "in one body" > how our Heavenly Father pleases to personally rule each of us, in our "hearts" < very personally, indeed > so we are sharing in His own peace which is His own harmony of Him in His love. In God's peace we have His almighty safety against various cruel things of fear and worry and hate and unforgiveness and dominating and dictatorial drives for pleasure which can not love us like God does. And in the ruling of our Creator's peace, He is sharing His creativity with us, for how to love each and every person.
So, how much are your tradition and homilies bringing attention to this which is right in your Canon Scripture?
