Here are some excerpts from Curt Daniel’s The History and Theology of Calvinism:
“There can be no doubt that by far the most influential proponent of historic Calvinism in Britain in the 20th-century was D.M. Lloyd-Jones. He was a Puritan born too late…was born in Wales and remained true to the best of his Welsh Calvinistic Methodism heritage for his entire Christian life…best-selling book Spiritual Depression…renowned for his ministry at the famous Westminster Chapel, only a few hundred yards from Buckingham Palace in London…wrote only a few of the many books that came out. Most were simply transcripts of his sermons, which were not usually pre-written…Some have said he was a preacher’s preacher, the best there is, a prince of preachers, a master of the divine art of preaching” (Curt Daniel, pp. 161-162).
“…Most of his books are lengthy series of consecutive expository sermons. He has a large volume of sermons on the Sermon on the Mount and another on Second Peter. His sermons on Romans 1 to 8 fill 7 volumes, and Ephesians has 8 volumes…Perhaps because of the somewhat mystical strain of his Welsh Calvinism, the Doctor was the main proponent of an unusual doctrine. He did not invent it; it was taught by a majority of Calvinists before him, such as Thomas Goodwin the Puritan. The doctrine said that the ‘sealing of the Spirit’ of Eph. 1:13 and 4:30 is a second work of grace after conversion. It was not the Pentecostal doctrine, nor the Wesleyan Perfectionist error, nor even the Keswick idea.
Lloyd-Jones said that the sealing brings full assurance of salvation. Before then, one only has faith, not certainty. When sealed in his conscience, the believer knows he has been saved. He argued from the KJV of Eph. 1:13 and Acts 19:2 that it is a second blessing. If he has seriously looked into at the Greek, he would have known better. Since his death, some have implied that this doctrine really meant that Lloyd-Jones was a closet Charismatic. Granted, he accepted that the gifts are occasionally present today, but he defined the sealing differently, and besides, he opposed the Charismatic movement” (Curt Daniel, p.162).
“Lloyd-Jones also opposed ecumenism and Neo-Evangelicalism. He refused to co-operate with the Billy Graham Crusade when it came to London. His strong ecclesiastical separation (not isolationism) is evident in the famous 1968 incident with John R.W. Stott. Stott and Lloyd-Jones were the leading names in the non-denominational Evangelical Alliance. At the 1968 conference, Lloyd-Jones publicly called on true believers to leave all denominations that are apostate or that tolerate apostates. This included the Church of England, of which Stott was a leading minister. After the Doctor was seated, Stott (who was on the platform as Chairman) rose and rebuked the Doctor. Only a few actually followed the Doctor’s call (such as Herbert Carson), but the main result was a split between the Anglicans and the others, including Independents, Baptists, and Presbyterians. This led to the formation of the rival British Evangelical Council. It also led to a partial split with Packer, who was co-host with Lloyd-Jones of the annual Puritan Conference. This would be re-organized and renamed the Westminster Conference, without Packer” (Curt Daniel, p. 162-163).
Stott not only denies the sovereignty of God, he also spits in the Face of Holiness and reproaches the propitiatory blood of Christ with his annihilationism doctrine.
Here is a link for Packer:
“His legacy lives on in the lives he touched. This is especially true in the Evangelical Movement of Wales, the vestiges of the old Calvinistic Methodism of George Whitefield and Daniel Rowland. Current leaders in this fine movement include Geoffrey Thomas (actually a Reformed Baptist), Hywel Jones, David Jones, and Graham Harrison. The Doctor also had a strong influence in the establishment of the Evangelical Library (London), the London Theological Seminary, and another organization that has been most responsible for the rebirth of the modern Reformed movement of historic Calvinism: the Banner of Truth” (Curt Daniel, p. 163).
