>Some of the traditions came out of old testament religion practices continued forward
Not sure which ones you're referring to, but at face value I'm a bit cautious since much of old testament ritual are things either centered around the temple or have been made irrelevant by the cross. I would also be weary of judaizing. Again, I could be way off the mark with those concerns, but that's just my gut reaction when reading that.
>and some were revealed to priests/bishops/etc. in a dream (not a joke).
I get that there is some process by which these "revalations" are supposed to be tested but we are rather explicitly told that God's word should not be added to. If a tradition requires some external revelation and isn't found "as-is" within scripture, I am incredibly skeptical of it at face value.
I do agree that there is value in tradition but not every tradition is valuable, and none rise to the level of scripture.
