I will also add that 2004 Synodical Resolution 3-06A had the following "resolves" about the report:
Resolved, That we commend the CTCR’s report, “Guide-
lines for Participation in Civic Events” for study to help
pastors, teachers, and church workers make decisions
about participation in civic events:
• That faithfully reflect our unqualified commitment to the
absolute truth of the Holy Scriptures as the Word of God;
• That seek to take full advantage of every legitimate op-
portunity to proclaim clearly in the public realm that
“only in and through Jesus do we have the definitive rev-
elation of the true and only God,” that God “is known as
Father and Savior only through Spirit-wrought faith in
Jesus Christ,” and that “only the Triune God—Father,
Son, and Holy Spirit—is the object of our worship and the
hope of our salvation” (GPCE p 8 );
• That honor and uphold the free and willing commitments
we have made with one another by virtue of our member-
ship in the Synod;
• That demonstrate concern and sensitivity for how partic-
ipation (or non-participation) in civic events may be per-
ceived by those inside and outside of the LCMS; and
• That recognize that “clarity in doctrine and practice and
charity in our dealings with one another are both essen-
tial to the church’s life and witness” (GPCE, p. 23); and be
it further
Resolved, That we encourage all the members of the
Synod to continue to study these issues under the guidance
of the Holy Scriptures and the Lutheran Confessions (see
Res. 3-04 on Theological Conferences) as we face the ongo-
ing challenges to bring God’s unchanging Word to bear on
our increasingly pluralistic and polytheistic culture.
