A couple of newlyweds kissing underneath the bride's veil.
The newlyweds are kissing in a church during the wedding.
In a wedding it cannot only be conducted in church.
Not everyone gets married in a church and newlyweds do not only kiss during the wedding.
The newlyweds aren't said to be in any one location, let alone in a church. Also, without a specific time frame the newlyweds could be kissing sometime after their wedding and not during the wedding.
