We know from ancient manuscripts that the antiphons were originally sung as people processed from church to church. In the first millennium, there were no parish churches as we know them today. Haghia Sophia (the great Church) was the Church of the city of Constantinople. Since the population may have reached a half million, though, they couldn’t all fit in the one church. Liturgies, therefore, were what we call “stational”. If the main Liturgy was at, say, the church of Saints Sergius and Bacchus, then the people would meet at another church, say, the Church of the Mother of God at Blachernae, then process to St. Theodore’s (the city was more compact than modern cities), then to Saints Sergius and Bacchus. As they processed they would sing a psalm with a troparion. At the next church they would then stop to say a litany and prayer. Then they went to another church, and finally to the main church of the day (this was almost always done in three’s). The last psalm with troparia was Psalm 94, which we have already noted was perfect for an entrance psalm, and has become our present-day Third Antiphon. The prayer that was said with the Third Antiphon was a prayer of entrance into the church: “Lord, our Master and God, who established orders and armies of angels and archangels for the service of your glory in heaven, make this our entrance an entrance of holy angels, concelebrating with us and glorifying your goodness.” This prayer is still said today. Later all these processions just dropped out, but the antiphons remained.
