So when Jesus tells his apostles in John 20:23 that they have the power to forgive sins in his name, did he not really mean it? Was he blowing smoke? Confused and befuddled? Ignorant of the higher concepts of Pauline theology?
Or maybe, just maybe, he was God in the flesh and knew exactly what he was saying.
C'mon, read the verse. 1 Tm 2:5 doesn't say that nobody can mediate between you and Jesus, it says that nobody can mediate between you and the Father apart from Jesus. If you read it in context, the chapter explicitly commands intercessory prayer, which is a form of mediation.
Wait, maybe Paul was dazed and confused, too! That's it, we'll take 1 Tm 2:5 all by itself, ignoring the rest of the chapter, and ignoring what Jesus said on the topic, and use it to reject that awful, icky, nasty Catholic church! That's what we'll do!
Reacting in a heated way accomplishes nothing. The passage is very clear -- There is ONE mediator between man and God = Jesus. It is very easy to understand.
