Dates of the Gospels

[Undeceived]

I was researching something or other about the Bible the other day and I read in passing that early Church Fathers never quoted the canonical Gospels. I was focused on something else at the time, but now that I've gone back to explore that area I've been surprised yet again.

Justin Martyr, a big time apologist, left behind some important works that were penned down around 150 A.D. In his works he refers to the 'Memoirs of the Apostles' but it's not exactly obvious if they are the canonical Gospels. Well, long story short, I read this article by an author who debunks every possibility of why it could have been the Gospels. I'm pretty convinced that the Gospels were penned down towards the end of the second century, which according to this author is basically when they were made 'known' in a historical sense.

Does anyone have arguments for/against the Gospels being penned down towards the second century?
