That is what distinguishes the NT church from Rome and other cultic sola ecclesia groups, in which examining the Scriptures to ascertain the veracity of RC teaching is not to be done by the faithful, as Scripture, Tradition and history are only what she says they are.
Certainly some of Scripture first existed in oral form, yet was established upon Scriptural substantiation in word and in power, as is abundantly evidenced. And as seen by a study of the "the word of God" (or the Lord) it can by assumed that wholly inspired Truth expressed in preaching was subsequently written.
While Scripture does not contain all that Christ did or can be know from God, (Jn. 21:25; 2Cor. 12:4; Rv. 10:4) yet Scripture is the only morphous body of Truth that is affirmed to be wholly inspired of God, and provides what is needed to instrumentally make man perfect, fully equipped for every good work. (2Tim. 3:15-17) By which all other Truth claims are tested by.
But that some of Scripture was first expressed orally does not mean that other oral teaching is wholly inspired of God, that does not make whatever is expressed orally is also inspired (and RC teaching states that the words in which Tradition has been passed down is not inspired). Yet Tradition is held by Rome to be the word of God based upon the premise of the assured veracity of Rome which declares it is so.
And under which all is declared to support her as needed.
Catholic doctrine, as authoritatively proposed by the Church, should be held as the supreme law; for, seeing that the same God is the author both of the Sacred Books and of the doctrine committed to the Church, it is clearly impossible that any teaching can by legitimate means be extracted from the former, which shall in any respect be at variance with the latter. Hence it follows that all interpretation is foolish and false which either makes the sacred writers disagree one with another, or is opposed to the doctrine of the Church.(Providentissimus Deus; http://www.vatican.va/archive/ccc_css/archive/catechism/p1s1c2a3.htm#104)
It was the charge of the Reformers that the Catholic doctrines were not primitive, and their pretension was to revert to antiquity. But the appeal to antiquity is both a treason and a heresy. It is a treason because it rejects the Divine voice of the Church at this hour, and a heresy because it denies that voice to be Divine...The only Divine evidence to us of what was primitive is the witness and voice of the Church at this hour. — "Most Rev."

Mandatory clerical celibacy was not institutionalized in the Church until relatively recently and for reasons which had nothing to do with anything that can be found in the Bible.
It may be argued there were political causes but that Paul advocated celibacy, yet as said, that was a gift, and to suppose all those called to be pastors have that gift is without warrant and presumptuous, and contrary to the normative state of the church, in which even most of the apostles were married.
Let's try some easy math:
There are approximately 1.2 billion Catholics world wide;
If merely 1% of them 'ask' Mary for help just once each day;
that means that 12 million separate prayers are headed Mary's direction every day.
Given that there are 86,400 seconds per day... (24 hours times 60 minutes times 60 seconds)
...that means that Mary has to handle approximately 139 'requests' per second!
Purty good fer someone NOT 'devine'!
