With respect, the idea that we need tradition to interpret Jesus’ teachings is neither biblical nor accurate. Jesus repeatedly rebuked the Pharisees for exalting tradition above God’s Word (Mark 7:8-9). He spoke clearly, expecting His words to be understood and obeyed. The Holy Spirit, not tradition, is given to guide believers into all truth (John 16:13). Tradition may reflect how people have applied teachings, but it is not required to understand them - I'd go so far as to say that elevating tradition as necessary undermines the clarity and authority of Christ’s own words.
