They are short clips of a much larger lecture. The maker of the clips obviously assumed that the listener would know what holiness is.
Here is a definition from the New Advent Catholic encyclopedia:
newadvent.org/cathen/07386a.htm
This was supposed to be in philosophy. How did the holiness of God lecture get moved to non Catholic Religions? It is very denomination neutral and focused only on the subject at hand. Sproul holds to the Apostles and Nicene Creeds as well. I didn’t see any forums about God at CA so I posted it under philosophy.
I’m usually impressed with the Catholic Encyclopedia’s articles but in this case I think the CCC comes closer to a fuller understanding, even if these quotes are a bit brief:
1709 He who believes in Christ becomes a son of God. This filial adoption transforms him by giving him the ability to follow the example of Christ. It makes him capable of acting rightly and doing good. In union with his Savior, the disciple attains the perfection of
charity which is holiness. Having matured in grace, the moral life blossoms into eternal life in the glory of heaven.
826
Charity is the soul of the holiness to which all are called: it "governs, shapes, and perfects all the means of sanctification.”
The CE mentions the necessity of keeping the commandments and separating from the world in order to be holy, which is true, of course, but I think more emphasis should be put on
love, which fulfills both of these.
In Sprouls first clip, he maintained that holiness should be the main attribute of God that we focus on, over and above some of His other attributes including
love. But this reveals perhaps a rather weak understanding of the term holiness, an understanding which is common enough but one which doesn’t edify as much as a deeper understanding would. To tell us that those in the presence of God are awed and humbled is to speak truth, of course, but in the experiences that God has granted to Catholic saints who’ve matured in their closeness to Him, the knowledge of an ineffably huge and unconditional love is the most overwhelmingly powerful aspect of being in His presence.
