That will be fine. I'll propose the 13th of this month as a starting date (this week will be very busy for me).
As for the introduction, this is my suggestion:
Included in the fruits of the first Ecumenical Council of the Christian Church, the First Council of Nicaea, is the Nicaean Creed. This creed, known as the ''Symbol of Faith'' was approved by the bishops in AD 325, and was used primarily as a testament professed by adult converts to the faith before baptism. Over the course of the following decades, changes were made to the Symbol of Faith by several persons and councils, the most notable of these are several changes made by what has become known as the Second Ecumenical Council: the First Council of Constantinople, in AD 381. Among the additions made to the Symbol of Nicaea, was a much-expanded section on the Holy Spirit (which the Symbol of Nicaea barely mentions). The being of the Holy Spirit, in the newly-created Nicaea-Constanapolitan Creed, is said to ''procede from the Father.'' The newly reformulated Creed fulfilled the same function as its predecesor: primarily, it was used as a liturgical testament of faith before baptism.
''Filioque'' is a Latin phrase translated ''And the Son.'' It was a clause added to the Symbol of Nicaea-Constaninople by a Western council held in the Iberian city of Toledo in the 6th century. in the insuing centuries, it was incorporated into the Western profession of the Creed, but not the Eastern. As a result, the Western version of the Symbol of Nicaea-Constantinople reads ''The Holy Spirit... proceeds from the Father and the Son,'' while the Eastern version reads ''The Holy Spirit... proceeds from the Father.''
[It would then be good to add links to the Nicaean Creed, and the Nicaea-Constantinoplitan Creed.]
