Interesting. The excerpt you posted had only references to Ephesians 1 and Romans 9. I think that it is a very nice take on Calvin's theology, and the very limited and misinterpreted Scripture that it is based upon.
Mark 16: 14 (But) later, as the eleven were at table, he appeared to them and rebuked them for their unbelief and hardness of heart because they had not believed those who saw him after he had been raised. 15 He said to them, "Go into the whole world and proclaim the gospel to every creature. 16 Whoever believes and is baptized will be saved; whoever does not believe will be condemned. 17 These signs will accompany those who believe: in my name they will drive out demons, they will speak new languages. 18 They will pick up serpents (with their hands), and if they drink any deadly thing, it will not harm them. They will lay hands on the sick, and they will recover." 19 So then the Lord Jesus, after he spoke to them, was taken up into heaven and took his seat at the right hand of God. 20 But they went forth and preached everywhere, while the Lord worked with them and confirmed the word through accompanying signs.) 3
Every creature, everywhere; the entire world. The Reformed God does not demonstrate great love, only limited love and limited mercy.
"Be not afraid; only believe." -- Mark 5:36
We agree that the Gospel should be preached everywhere to everyone. No one disputes that here. God shows His great love by choosing to save even ONE of us since none of us can merit Heaven. There is no Biblical rule saying that God can only have great love if He loves all people equally. That rule was invented by men. The truth is that God does indeed have great love for His children. However, the Bible is clear that not all people are God's children.
And when you criticize "limited love" and "limited mercy" don't forget that your own versions of God's love and mercy are VERY limited too in that you require acts of men to get (or earn) that love and mercy. Our view limits grace and mercy to God's sovereign will in choosing His elect (your view does not), and the Catholic view limits them to man's decisions to comply with requirements using their free wills (our view does not). So, if you see limitations on God's grace and mercy as being a bad thing, then the Catholic God is in the same boat as the Reformed God.
