About IRBS

A Welcome From President Renihan

Dear Christian friends,

Welcome to the website for International Reformed Baptist Seminary. Thank you for taking the time to visit our site and learning about what the Lord is doing among us. An internet site cannot convey the warmth we wish to express, so we ask you to receive our words which express a genuine desire for the Lord’s blessing on your life.

IRBS is soon to celebrate its 25th anniversary. For twenty years we existed as an institute affiliated with Westminster Seminary California, and in 2018 developed our programs into a full seminary curriculum in our new location, Mansfield, Texas. We are committed to the infallible and inerrant Word of God, and joyfully subscribe to the Second London Baptist Confession of Faith, often called the 1689 London Baptist Confession. By God’s grace, our pledges to these documents are strong and firm and will remain so.

The Lord has allowed us to bring together an excellent faculty of pastor-scholars who together seek to honor Christ in their teaching ministries. These are experienced men who shepherd God’s flocks with loving concern. We are united in our devotion to Christ, His Word, our Confession and the task of preparing able ministers of the New Covenant (2 Corinthians 3.6). Each faculty member is available to assist students in their coursework as well as their ministry and personal questions.

Students may enroll in a variety of programs at IRBS, including the standard degree for ministerial preparation, the Master of Divinity, a two-year Master of Arts in Religion, the Certificate of Reformed Baptist Studies, a Diploma program for mature students who do not have a baccalaureate degree, as well as special opportunities for visiting students. Our flexible hybrid programs offer students the opportunity to study on campus as well as virtually in their own homes. Most classes are offered live in the classroom as well as via livestream. We hope that even our distance students will be able to enter into the live classroom experience.

We hope that you will find your visit here to be not only informative, but also the first step in getting to know us better.

May Christ be glorified!

In His name,
James M. Renihan, Ph.D.,


IRBS wants to assure its students and prospective students of its high academic standards and integrity. While even now operating at such standards, the seminary is pursuing official accreditation.

“By the Holy Spirit who dwells within us, guard the good deposit entrusted to you.”

– 2 Timothy 1:14

Our Mission

The Need

Scripture is clear. The church must be actively involved in the spread of the Gospel (Matt. 28:18-20); Christ gives ministerial gifts to His churches for growth and edification (Eph. 4:11); God's Word commands Christian ministers to be actively involved in the training of their successors (2 Tim. 2:2).

Serve Churches

Serving not only Reformed Baptist churches, but churches at large, our goal is for students from around the globe to study with our school and return to their churches prepared to further the cause of Christ.

Serve the Globe

IRBS serves a global constituency, offering the Master of Divinity degree which provides robust academic preparation in the necessary theological and ministerial disciplines.


International Reformed Baptist Seminary has an ever-expanding list of partners that aid in providing confessional and biblical theological training to future pastors across the globe. If you are interested in more information, contact us today!

Confessional Subscription & Foundation

IRBS is a fully functioning residential and online confessional Reformed Baptist Seminary. We subscribe to and are grounded in the doctrine and practice of the Word of God as reflected in the three great seventeenth century Particular Baptist confessions: the First London Baptist Confession of Faith of 1644/46/51, the Second London Baptist Confession of 1677 (often called the 1689 Confession), and the Baptist Catechism of 1693.

These excellent documents provide a summary and just exhibition of the system of doctrine and religious belief which we believe is contained in the Holy Scripture, and revealed by God to man for his salvation. The Second London Baptist Confession is our primary confession of faith.
