So it was because of Luke's close association with Paul that was a primary reason that it was considered inspired? Weak.
You are aware that an association with an Apostle is the is also the reason that the Gospel of Mark is considered inspired, aren't you? Do you object to it as well? It is fairly well accepted that the Epistles of St Peter were not written by Peter himself, but by someone under his authority. It is this Apostolic connection that leads us to accept the Epistles as Scripture.
I'd like to see a source for St Clement,
1 Clement, Chapter 13 (Compare this with Luke 6:36-38)
For thus He spoke: "Be ye merciful, that ye may obtain mercy; forgive, that it may be forgiven to you ; as ye do, so shall it be done unto you; as ye judge, so shall ye be judged; as ye are kind, so shall kindness be shown to you; with what measure ye mete, with the same it shall be measured to you."
1 Clement, Chapter 24 (cf Luke 8:5)
The sower goes forth, and casts it into the ground; and the seed being thus scattered, though dry and naked when it fell upon the earth, is gradually dissolved. Then out of its dissolution the mighty power of the providence of the Lord raises it up again, and from one seed many arise and bring forth fruit.
St. Ignatius also quoted Luke in the beginning of the 2nd Century.
If I might ask, what are your criteria for the recognition of Scripture?
