God needs all of his attributes to really be God. To ask whether holiness or love is God's "primary" attribute is like asking which of your cars tires is the primary tire. If any one of them is missing the car ceases to function as a car ought. Why stop with love and holiness? These are probably chosen because we find verses that state these attributes very clearly (i.e., God is love; be ye holy for I am holy). However there are pleanty of other verses that put forward other characteristics of God. Two weeks ago, I asked some of our youth group to give me some verses that tell us to be like God in some way. Holiness and love were two of the first that came up, but here are a couple more: Ephesians 4:32 - forgive like God forgave you (also Matt. 6:12, 14-15) Matthew 5:48 - perfect as God is perfect (this means mature in actions and choices) *Feel free to add others.* If Matt forced me to choose one or the other, I would have to pick holiness as the greatest of the attributes. Biblically because of the angles' three-fold declaration in Isaiah 6. Theologically because all the other attributes seem to be held together by God's holy (blameless, perfect, predictably righteous) practice of all His other attributes. BTW-I think Llywn is on the right track, but defining holiness as the "divinity of God" makes it hard for us to be holy like he is holy. Not a debate, just a helpful thought.
