Well if an Apostle of Jesus “exhorts” one to follow sound doctrines of the Church as handed down either through the deposit of faith or what Jesus taught them why would I not heed them?
from the Merrian-Webster online dictionary:
: to try to influence (someone) by words or advice : **to strongly urge (someone) to do something
Some doctrines require a lot of studying and pondering and even then, we might only achieve a partial understanding of them.
That’s why they are referred to as “Misteries of Faith”.
If I believe them is because I put my faith and trust on the word of Jesus and His Apostles.
Some aquiesence of the will is required, and it is fitting that it should be so.
God over and over in the Bible tells us that we are a “Stiff necked people”
We need to learn to humble submit sometimes, and ask God for the gift of wisdom to understand these misteries AND the gift of patience if we cannot fully grasp them, not to mention asking to redouble our dose of Humility in the meantime.
