It's more that the Church's perspective must be accepted in order for the Scripture to have power. Or something.
I mean, honestly, the church plays an integral role in the growth and resolution of one's faith - that's why Paul wrote Titus and 1Timothy and so on. The church is present in dealing with members of the faith that aren't truthful (Acts), deep into sexual immorality (1 Corinthians), and so on. And the members of churches must be directed in accordance to "sound doctrine" from the church elders. (Titus)
To say, though, that the interpretation of the Bible is based on doctrine and tradition, rather than doctrine and tradition based on the Bible, seems foolish to me. Furthermore, to suggest that church doctrine is infallible, yet directed by a man that is fallible, is silly.
