One would think one important topic on the Rite of Confirmation would be the public confession of the doctrine of the Evangelical Lutheran Church to be faithful and true. This is a requirement for individual and congregational members of the Missouri Synod, and it is required in constitutions of LCMS congregations for communicant members.

This public confession is also important because it is part of the understanding by the Evangelical Lutheran Church and the Missouri Synod of the doctrine of closed communion.

Yet this public confession by the confirmand doesn't seem to be mentioned in the above article. Further discussion about the significance of this public confession in the Missouri Synod is discussed in the article, The Lutheran Confirmation Vow.
