This is an excellent presentation that pretty much lets Baxter speak for himself with regard to his explicit rejection of justification by faith alone, endorsement of justification by faith+works, and the inseparable nature of his doctrinal and practical works.
One huge question central to any debate over covenant theology is whether or not the Mosaic covenant was an administration of the covenant of grace whereby sinners are saved (let alone the question of what an “administration” actually is). While many modern Reformed Baptists say yes, the Mosaic covenant was substantially the covenant of grace, Benjamin Keach disagrees, as we see in this post from Sam Renihan at Particular Voices.
More Particular Baptists fighting the Federal Vision heresy before it was even formed. There’s nothing new under the sun, and that includes attacks on the doctrine of Justification by Faith Alone.
