I really agree with alot of what you have written; in fact, at times whilst reading / posting here, I have been tempted to open a similar topic (... or just bellow out loud, "BUT AREN"T WE MISSING THE WHOLE POINT)!?!
- There are a great number of helpful, edifying, instructional, charitable exchanges to be encountered in a forum such as this, and I have have been personally encouraged by many postings of just this sort.
In a free interchange of ideas, of course, there are always going to be many points of view and personalities -
So, I suppose, it may be par for the course that, as in all the centuries of the Church and of humanity, there's a certain tendency among some to "get hung up" on certain things -
The End Times, "diverse doctrines", The Council of Chalcedon, Protestant, Catholic, or Orthodox (and, therein, Old or New Calendar, or Charismatic vs. Evangelical or "Mainline", or Sedavacantist - Tridentine "with permission" - Novus Ordo), and of course issues of morality and how it is to be followed, implemented, legislated, etc. -
... eventually, one might think, "Is this what Christ and his Church is all about"?
- and, then, perhaps, a person might be led to study the Scriptures, as you have done, and to ponder the tachings of Our Lord as we receive them in the Gospels, the other scriptures and examples from the Lives of Christ and the saints -
This is the point where I get stuck. I think that you are on to something about focusing on "the one thing needful", following Christ, which is a decision we all make daily (and more), and which has to made again and again and again -
and we fall, we all do (I know I do, anyway, pretty much constantly) but we can get up again and keep on going, and follow Christ Our God, who is Compassionate and Merciful.
(I've been reading "The Parables of Peanuts", based on Charles Schultz's often strikingly wise and theologically deep comic strip; the author of the volume has some interesting reflections on hypocrisy, "vulture evangelists", and how hellfire and damnation can actually become an idol, replacing God Himself, by those who are not as infinite in Mercy as He).
