This is classic evangelization, a mission given by Christ to the Church and approved by the Church as part of the role of the laity.
From reading Mark’s website, I think it goes a little bit beyond classic evangelization as taught by the Church.
I do not know much about Mark Mallett - but it is always prudent to not be so quick to pass judgement on fellow Catholics.
I too don’t know much about Mark Mallet, other than what I’ve read at his web-site, which came to my attention through this thread.
However from the link you posted; Bold my emphasis.
**The Holy See entrusts this present document to the pastoral zeal of diocesan Bishops in the various particular Churches and to other Ordinaries **in the hope that its application may produce abundant fruit for the growth, in communion, of sacred ministers and the non-ordained faithful.
The Holy Father reminds us that, “**the particular gift of each of the Church’s members must be wisely and carefully acknowledged, safeguarded, promoted, discerned and co-ordinated, without confusing roles functions or theological and canonical status”. **
There are more serious things to be concerned about such as proclaiming the good news to the lost as Jesus taught us.
Proclaiming the Good News is classical evangelization, as approved by the Church.
Proclaiming personal spiritual experiences as prophecy or self interpretation of scripture, are not.
