The Catholic Church has both saints and sinners. Jesus taught sinners so that they could have eternal life with Him and some did and some didn’t like Judas and those that didn’t believe in the Real Presence.
Certainly, the Catholic church continues to have sinners, even Popes just like Judas one of the Apostles.
The Catholic Church also continues the sacred traditions taught by Jesus and Apostles that were oral teachings and not written in the Bible.
What is Tradition?
In this discussion it is important to keep in mind what the Catholic Church means by tradition. The term does not refer to legends or mythological accounts, nor does it encompass transitory customs or practices which may change, as circumstances warrant, such as styles of priestly dress, particular forms of devotion to saints, or even liturgical rubrics. Sacred or apostolic tradition consists of the teachings that the apostles passed on orally through their preaching. These teachings largely (perhaps entirely) overlap with those contained in Scripture, but the mode of their transmission is different.
They have been handed down and entrusted to the Churchs. It is necessary that Christians believe in and follow this tradition as well as the Bible (Luke 10:16). The truth of the faith has been given primarily to the leaders of the Church (Eph. 3:5), who, with Christ, form the foundation of the Church (Eph. 2:20). The Church has been guided by the Holy Spirit, who protects this teaching from corruption (John 14:25-26, 16:13).

This should really help you with the details ...
The apostles did NOT pass on any oral traditions to anyone after the scriptures were written...This is proven by the fact that none exist...
Catholic traditions do not overlap the scriptures...Catholic tradition contradict clear scripture as has been shown a gazillion times...
