Of course. Christ promised He would reveal God's truth to us through this medium - the Apostolic community.
God promised (in Jeremiah 29) that all that sought Him ... would find Him. Is this the assurance you are looking for ?
Of course people will find God whom look. And as such, they will seek out His community as a result.
I do not believe that the Church has lost the truth. I just don't believe that the Catholic Church (or any other particular segment of the Church) ... has all of the truth.
Me neither. It has the fullness of God's revelation - but not all of it, because God has not revealed EVERYTHING to us yet.
When asked a question, or challenged, (as He often was) Jesus would always appeal to the scriptures (i.e. It is written, What saith the scriptures ..., Search the scriptures, etc.)
ALWAYS? He often times referred to HIMSELF as the Law, such as in Matthew 5 - "You have HEARD (NOTE, He doesn't say, 'you have read...') it said, but I tell you..."
To make scripture the basis for one's chrisitan life and ministry.
I am not aware of anything that Catholics do that is AGAINST Scripture. Scripture and Apostolic Tradition, both being from God, cannot contradict.
There is obviously some caveat here ... for if the Apostles had rigidly followed the Pharisees ... they wouldn't have been following Jesus ... for the Pharisees opposed Jesus.
Jesus tells them to obey them, but not their hypocrisy. He is speaking of the Pharisees and their interpretation of the Law, not in who Jesus was.

I don't recall where Jesus referred to Himself as the Law.
But He did use the formulation you speak of quite often ... "you have heard, ... but I say unto you ..."
He, typically, would use this formulation to correct some point of misinterpretation (or shallow interpretation) ... of God's word to men.
