Two Short Catechisms (1645)

Written for his congregation at Fordham, Essex, Owen presents two catechisms surveying the essentials of Reformed Christianity. The shorter form teaches children and new believers the core of Scripture, God, Christ, faith, repentance, and the sacraments in simple Q&A. The larger catechism unfolds 26 doctrinal chapters — from divine decrees and creation through Christ's threefold office, justification, sanctification, church polity, and believer's privileges — with pointed scripture proofs and marginal notes defending Calvinist orthodoxy against Arminian and Romanist errors.
