Visiting another parish, can you... [Rom-Cath]?

Of course, the Catholic Church is One. the church, may I remind you, is not a building, or a parish, it is the PEOPLE. Catholics are not "visitors" in any parish, they are simply Christians, and every single parish anywhere in the world is their spiritual home. Being Anglican, just think of the Catholic Church as something very similar to the Anglican Church, there are so few differences in practise, that you would be amazed.

Of course. A Catholic who is free of mortal sin can take Communion at any parish.

Of course - I can receive Holy Communion in any Catholic Mass around the world.

if that roman catholic is in a state of grace.. you betcha... that the beauty of the uuniversal chruch ..you can find the eucharist in a catholic church almost everywhere in the world... and know thats the theological teacings are all identical.

Anywhere in the world.

Catholicism: Don't leave home without it.

yes

as long as they believe in the sacrifice of the heavenly father, jesus christ, and the holy spirit
