I too am baffled by the idea that a Catholic would even want to be married on Holy Saturday.
If one were to entertain the idea, as unusual as it is, there are many things one would have to consider.
A wedding is a public event and anyone may attend. Therefore, all those who attend the Vigil Mass would attend the hypothetical wedding. Our Church is quite full at the Vigil, so imagine having all those extra people at the wedding. You’d likely have a complete stranger sitting by Aunt Mabel and a whole family you don’t even know sitting by Grandma and Grandpa. Looking at wedding pictures later would be interesting since so many strangers would be in the Church.
Would wedding ushers seat all those extra people? Would guests join the standing room only crowd at the back of Church? Would the wedding party be seated in the folding chairs in the aisles so they can at least stay somewhat together and so the photographer can see them?
Would the ring bearer and flower girl fall asleep before the end of Mass? Would they get cranky and fidgety during a lengthy Vigil Mass that may last around 2-1/2 to 3 hours or so and sometimes more at some Churches?
Would the wedding processional take place after the lights come back on after all seven of the readings and after the psalms, prayers, Gloria, opening prayer, epistle, alleluia, gospel, homily? Or, would it take place in the dark and the wedding party would process in with everyone else who processes in after the blessing of the fire?
Would wedding vows be exchanged before or after the renewal of baptismal promises?
I could go on, but I think my attempt at humor might be getting a bit much at this point.
