It was at the Council of Hippo in 393 AD that the Church determined the composition of the Bible. It is not theĆ Bible that makes the Church, but the Church that made the Bible. Jesus never wrote; rather than passing on writing, He passed on His Spirit.
Tradition is what Christ taught His apostles and what His apostles passed down to us. Sources of Tradition are Church Fathers during the first 600 years of Christianity; what has always been taught everywhere and every time; the statements of the Bishops when united with the Pope; and statements by the Pope made from his office per the guidelines outlined at Vatican I
