Saint John’s words at the end of today’s first reading (2 John 4-9) are clear:
Anyone who is so “progressive”
as not to remain in the teaching of the Christ
does not have God;
whoever remains in the teaching
has the Father and the Son.
It is necessary, of course, for all of us to progress continually in our knowledge and living out of the teaching of Christ and it is valuable to progress in our knowledge of many other things, but we must always remain rooted in reality and faithful to Christ or else we will “progress” into oblivion.
