Where There Are Two Or Three Gathered.....

Over the years a number of ecumenical catholics have used the following quote to defend non-Catholic christians to me;

For where there are two or three gathered together in my name, there am I in the midst of them.
St Matthew XVIII, 20

I was so happy to find the following footnote in my old pocket New Testament;

'There am I in the midst of them.' This is understood of such assemblies only, as are gathered in the name and authority of Christ; and in unity of the church of Christ, St Cyprian de Unitate Ecclasiae
