There could be a number of reasons for this…
I believe that the main reason for it is that the Church, for so many centuries, was either the “Faith of the realm” and as such everyone was Catholic, or it was NOT the faith of the realm and as such - it was dangerous to be Catholic in that Realm…Such an environment is not conducive to such evangelization efforts.
This of course has changed in most places, but the mentality - of being an “established church” and families raising their children up in the faith etc. is a strong one.
So there is this sort of mentality, especially among cradle Catholics, that says, “That’s just not what we do”…
At least that is my thought…
Do Catholics not go door-to-door or open-air preach?
If now, how is evangelism done? The process of preaching the gospel in the great commission?
Others have addressed this quite nicely so far.
I do think that, as time goes on, the Church will develop more evangelism programs, but I also think that she will wish to avoid those things that most people find “annoying” and off putting…One of which is door to door evangelism.
