You said, “The guiding force of Men’s meeting is the longing to have a kind of democratic administration of a Church and a desire of the members to have a role and say in the decision making process.”
By democracy we usually mean, governance by elected representatives. I wonder if that is what you implied by your statement above. If so, then that concept is completely unscriptural. In the church, there only One Head who governs, that is Christ. Church members submit to the Head, just as individual body parts submit to the physical head of the body.
Having said that, if you may have used ‘democracy’ to imply decision making dynamics, then democracy is not the right word. A better term is ‘congregationalism’ in which every member of the congregation has a voice in the decision making process.
A proper review of the concepts and terms used in NT will lend much support to the congregational set up of a church polity. There are numerous articles and books you can read, if you are interested. Church leadership is meant for “service” and it is expressly not for executive powers and decision making (with certain caveats, of course). The Lord did not intend for the elders of a church to exercise “authority” and “lord” over His body. Unfortunately, many churches allow this to happen.
Now, on a practical basis, it is more efficient and orderly to delegate decision making to certain individuals, depending on the scope what is being decided. All members are not necessary for every decision made in a church – most decisions can be made by the elders, who are trusted by the congregation to do so. But here is crucial point – Every member has a scriptural right to express his or her voice on all matters of the church. That fundamental right of every believer is implied when Paul appealed to the Corinthian believers, “Now I plead with you, brethren, by the name of our Lord Jesus Christ, that you all speak the same thing, and that there be no divisions among you, but that you be perfectly joined together in the same mind and in the same judgment (1 Cor 1:10)”
If all believers were meant to blindly follow the dictates of a couple of elders, Paul would have no need to write as he wrote above. The scriptural direction is for every believer to come together with other believers, surrendering and submitting to the Spirit of God, and jointly make decisions, in the leading of the Spirit of God. Such decisions are not “democracy”, because every believer is seeking to prayerfully unite under the leading of Spirit of God, putting aside selfish motives (that are a hallmarks of democratic set ups) and embracing outcomes that will most benefit others (and not themselves), thus, bringing glory to the Lord.
For example, in Acts 4:32, the decision to sell everything and share their proceeds with each other was made by each believer and was not forced on them by anyone in authority (i.e. apostles or elders). It was painful to each one, but they were able to unite together in that decision. That is the scriptural model – not easy to follow, but we cannot dilute scriptural principles, with our own inventions.
