A Confessional Reformed
Baptist Seminary With Global Reach

Welcome to IRBS

International Reformed Baptist Seminary (IRBS) is an Independent, Confessional, Reformed seminary based in Mansfield, TX with an ever expanding global reach.

The seminary exists to partner with churches in preparing godly men for Gospel ministry. This is done through the teaching of God’s inerrant, infallible, and inspired Word tied together with hands-on practice in the local church.

Academic Preparation

A firm foundation of truth and wisdom is vital for Gospel ministry. A master's degree from IRBS therefore ensures thorough preparation for work in Christ’s churches.

Practical Training

Theology must be put to practice in the church. For this reason, IRBS stresses internship with local churches to provide guided growth and experience in pastoral duties.

Outstanding Faculty

Instruction from eminently qualified men lays the groundwork for a faithful ministry. To this end, our students sit under some of the best theological minds and pastoral hearts in the Reformed Baptist world.

Robust, Pastoral Training

Gospel ministry is demanding and IRBS is committed to preparing men for that task. Our programs are robust and conducted by expert pastor-scholars who know first-hand the requirements of serving the Bride of Christ. Through the employment of lecture-based courses and internships, International Reformed Baptist Seminary graduates men ready to serve in churches around the world.

Our Mission & Purpose

The Bible teaches that the church must be actively involved in the spread of the Gospel (Matt. 28:18-20) and that Christian ministers are to be actively involved in the training of their successors (2 Tim. 2:2).

IRBS exists to fulfill that need through educating and training individuals for ministry through graduate level theological studies in North America and around the world.

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.,
