Different views on church and ministry

I've been watching an LCMS TV YouTube channel and was wondering what the main difference(s) are between WELS and LCMS Lutherans? I heard that one of the main differences is how we view the office of the ministry, but I do not understand this well. Can you elaborate? Thanks.

I will let the two synods speak for themselves, citing statements from their church web sites.

The Lutheran Church Missouri Synod states: “With respect to the doctrine of the ministry, since the days of C.F.W. Walther our Synod has held that the office of the public ministry (the pastoral office) according to Scripture is the one divinely established office in the church, while the church possesses the freedom to create other offices, by human institution, from time to time to assist in the carrying out of the functions of the pastoral ministry.”

WELS states: “Christ instituted one office in His Church, the ministry of the Gospel. It is the task of proclaiming the Gospel in Word and Sacrament. Mt 28:18-20; Mk 16:15; Jn 20:21-23; Ac 1:8; 1 Pe 2:9; Lk 22:19,20. This office or service, the ministry of the keys, has been given to the Church, i.e., to the believers individually and collectively. Mt 16:19; 10:32; 18:18; 1 Pe 2:9.

“There is, however, no direct word of institution for any particular form of the public ministry. The one public ministry of the Gospel may assume various forms, as circumstances demand. Ac 6:1-6. The specific forms in which Christians establish the public ministry have not been prescribed by the Lord to His New Testament Church. It is the Holy Spirit who through the gift of their common faith leads the believers to establish the adequate and wholesome forms which fit every circumstance, situation, and need. Various functions are mentioned in Scripture: 1 Ti 4:13; Eph 4:11; 1 Co 12:28; Ro 12:6-8; 2 Ti 2:2; Jn 21:15-17 (feeding); Ac 20:28 (watching); 1 Ti 3:2; 4:11; 6:2 (teaching); 1 Ti 3:5; 5:17 (ruling). In spite of the great diversity in the external forms of the ministerial work, the ministry is essentially one. The various offices for the public preaching of the Gospel, not only those enumerated above, e.g., in Eph 4:11 and 1 Co 12:28, but also those developed in our day, are all gifts of the exalted Christ to His Church which the Church receives gratefully and with due regard for love and order employs under the guidance and direction of the Holy Spirit for the upbuilding of the spiritual body of Christ; and all of them are comprehended under the general commission to preach the Gospel given to all believers.”

You may be aware that representatives of LCMS, WELS and ELS have had informal discussions the past few years to understand better each other’s positions on this and other subjects. It is our prayer that God bless those and future discussions.
