I would highly recommend the book "A Faire and Easie Way to Heaven: Covenant Theology and Antinomianism in Early Massachusetts" by William KB Stoever. He notes Crisp many times in this book and it seems to be well documented.

In it is provided a helpful "thumbnail" of 17th century antinomianism. "Antinomians were held to maintain that the consciences of believers are not bound by the law and that God sees no sin in Christians; that assurance once obtained is not to be doubed of; that justification is before faith and that faith is a discovery of justification; and that sanctification is no evidence of justification." (p.232 n.11).
