About us

Short Description

Theological Teaching-Service is a interdenominational small and effective mission association supported by all different kinds of churches. We stress the substance of Biblical truth and we are part of World Evengelical Alliance.

Theological Teaching-Service – the name equals the program. As a service we go to the people where they live and offer them trainings of knowing the God's Word better and we teach them how to apply it in this world. We do not teach a certain way of interpreting the Bible. The Bible alone is the means by which we teach.

  • It is not our intention to create certain changes. We leave it to God and His Word to bring about changes.
  • Therefore Church traditions are respected - Biblical doctrine creates changes.
  • Answers to todays questions will be found by intensive study of the Bible.

Theological Teaching - Service has ministered for over 20 years in East and South East Europe. Because we respect foreign cultures and can easly adapt, we gained credibility. This is evidenced by many invitations and recommendations.

Theological Teaching-Service does not bring presents but the Word of God. We teach Bible knowledge to Church laymen and pastors and train up spiritual leaders. For this purpose we use all kind of modern media but outlines are never handed out. We are convinced that by listening, watching and writing down notes the greatest learning is achieved.

Theological Teaching-Service has a transparent administration. We keep people informed through reports.

Theological Teaching-Service is the German branch of World Reach Inc. It is a faith based mission trusting God to provide the financial resources necessary to do the work of ministry. Because every team member is responsible for raising his own financial support and each giver knows exactly whom and / or what he supports.

The strategic goal of Theologische Schulungs-Service (World Reach Europe) is to teach Christians in their linguistic, cultural and social environment in association with local Churches how they can:

  1. grow in faith
  2. reach out to others and win them for Jesus
  3. become able to fulfill their various tasks in Church
  4. train and disciple others.

This strategy can be applied to all cultures and countries.


Theologischer Schulungs-Service e.V. (World Reach Europe) is a “faith” ministry, trusting God to provide the financial resources necessary to do the work of ministry. All team members are responsible for raising their own financial support to sustain their public ministry and private lives. The amount of support necessary for this is defined by the Board. Financial support for a team member may come from a variety of sources based on his personal contacts.

All donations are used for the designated purpose. However, an administrative fee is assessed (12 % in the States, 5 % in Europe) to help cover costs to promote Mission work. On your donation, please indicate, how you wish the funds to be used.

Doctrinal Statement

We believe:

  • That the Bible, consisting of sixty-six books of the Old Testament and New Testament, is the inerrant and complete Word of God, the final authority in all matters of faith and practice. (2 Tim. 3:16-17; 2 Pet. 1:20-21; Jude 3)
  • In a God, who is eternal, a threefold person: Father, Son and Holy Spirit (Deut 6:4/Mt-28:19/Lk.3:21-22)
  • That Jesus Christ is God´s only son, conceived through the Holy Spirit , born of the Virgin Mary and he was truly God and truly man ( Lk.1:30-35/John 1:18/3:16/Phil.2:5-11)
  • That man was created in the image of God, that he sinned and through his sin caused not only bodily death but also spiritual death, by which man now is separated from God. Man's nature is sinful and he is a sinner in thoughts, words and deeds. (Gen.1:26-27/2:16-17/3:6-19/Rm.3:10-23/7:18/11:32/Gal.3:22)
  • That the Lord Jesus Christ died as a substitutionary and complete sacrifice for the sins of the whole world and that only those who believe in Him are saved, and this on the basis of His shed blood. (Rom. 3:24-28; 5:8-10; 1 Tim. 2:5-6; 1 John 2:1-2)
  • That the Lord Jesus Christ arose from the dead in the same body in which He was crucified; that He ascended into heaven in His resurrected, glorified body and is now exalted at the right hand of the Father as Head of the Church. (John 20:1-19; Acts 1:9-11; Eph. 1:20-23; Heb. 1:3)
  • That both the believer and unbeliever will be resurrected bodily in their own order: the saved unto everlasting bliss; the lost unto everlasting and conscious punishment. (1 Cor. 15:1-50; 1 Thess. 4:13-18; Rev. 20:11-15; 21:22)
  • That on the sole condition of personal faith in the Lord Jesus Christ, men are born again by the Holy Spirit; that at regeneration, all believers in this age are indwelt by the Holy Spirit, baptized by the Holy Spirit into the in the Body of Christ and sealed by the Holy Spirit unto the day of redemption. (Rom. 3:24-28; 8:9-11; 1 Cor. 12:13; Eph. 4:30)
  • That sanctification, which is separation unto God, is threefold: positionally, the believer was sanctified at his conversion by virtue of his union with Christ; progressively, he is continually being sanctified through the Word as he walks in the Spirit, thereby overcoming the lusts of the flesh and producing the fruit of the Spirit; ultimately, he will be completely conformed to the image of Christ when he sees his Savior face to face. (John 17:17; Eph. 5:26; Col. 3:1-4; Heb. 10:14; 1 John 3:1-3)
  • That the Lord Jesus Christ will come after his Church, which is His Body, at the end of times. Later He will return to this earth personally, visibly and bodily. (John 14:3; Acts 1:10-11; Eph. 1:22-23; Phil. 3:20-21; 1Thess. 4:13-18; Titus 2:11-14, Heb. 9:28)

We as Theological Teaching Service (TSS) provide you the following subjects. We like to adjust to your and your Churches needs or even develop new curricula for other topics.
