I'm aware of a lot of so-called experts who from time to time peddle fashionable and often dissenting and thin theories contrary to the constant teaching of the Church dating all the way back to the founding fathers. 

I'm aware also that they like to publish books, get on the $peaking circuit$ as well. 

These experts don't move the needle.  And their sycophantic following don't move me either. 

Mary Magdalen was never referred to as disciple or apostle.   She was a great friend. 

And I also am aware that it's very fashionable to refer to the Gospels with names like "Lucan" and "Johannine" in order to give the writer sort of an air of scholarship not merited.

I like to refer to the Evangelists with their saintly/heavenly names:  
The Gospel of Saint Matthew (why abbreviate, yes? Spell out Saint!)
The Gospel of Saint Mark
The Gospel of Saint Luke
The Gosepl of Saint John.

Saint Matthew, pray for us.
Saint Mark, pray for us.
Saint Luke, pray for us.
Sancte Ioánnes. Ora pro nobis.
