Boyce remains one of the most influential voices of mid-19th century Baptist life. Though a hard-line strict Calvinist through and through (i.e. TULIP), 19th century American Baptist theology could not be understood apart from Boyce.
Cottrell is one of the best non-Reformed theologians writing theology. Albeit his polemical adherence to Disciples of Christ theological distinctness, it would be a mistake to dismiss him.
