What happened at Pentecost is described by the evangelist Luke in the Acts of the Apostles as follows: "Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. 3 They saw what seemed to be tongues of fire that separated and came to rest on each of them. 4 All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them. (NIV, Acts 2-2-3)
This spirit in common reminds us, that the Sunday service and the work of the church, in general, should be open to everyone. Worship is a shared celebration of all who come together to celebrate. Not only the work of a vicar and some few members. This can be remembered most especially around the day of Pentecost.
In a group in your ChurchDesk you can gather people who want to think about the service in advance. In good time before the service - about two weeks - pastors can post the Bible text on which the sermon is to be preached and record the group's discussion. Of course, you can also collect suggestions about which Bible text or sermon topic the congregation would like to hear. The finished sermon text can be kept in the document repository and, of course, published on the website afterwards for future reference.
ChurchDesk forms on your own website are a good and easy way to collect intercession requests for the service. This can also be anonymous, as you wish, as names are not a mandatory field. You can set this up individually in the forms. You can refer to these ideas in your church newsletter, link to the sermon to read, and share the summary of a service follow-up with the whole congregation.
