Since the new translation they now say "Repent and believe in the Gospel" or "Remember that you are dust, and to dust you shall return.", either one is acceptable.
The " catholic " in the creed has a lower case C..... therefore this is the universal church, not the actual Catholic Church. So catholic = Universal Church Catholic = The Catholic Church ( The one with the Pope )
The 'Day of Ashes' or Dies Cinerum began in the 6th century AD by the Roman Catholic Church. Many say it began by Pope Gregory the Great (590-604 AD). Naturally, as the most powerful and largest Church, it spread through the Empire. During the Protestant Reformation, many if not all of the 'daughter' churches kept this custom on the calendar.
Saints (Sts.) Peter and Paul Catholic Church would be proper.
The Anglican Church is not called the Anglican Catholic Church, and the Catholic Church is not formally known as the Roman Catholic Church even though the Vatican is indeed located in Rome. Your question therefore would more accurately read, can an Anglican priest say Mass at a Catholic Church. The answer is, the Catholic religion does not allow Anglican priests to officiate at their rituals. The Anglican Church, despite being extremely similar to the Catholic Church in most respects, is nonetheless regarded by Catholicism as a heretical schism.
No. While Ash Wednesday is an important day to Catholics as the beginning of the season of Lent, it is not a Holy Day of Obligation. Ash Wednesday is however a special holy day and a day of abstinence and penance.
The Catholic Church was first... so, I guess you could just say "chrsitianity" or you could say the Catholic Church.
Not much specifically, the Catholic Church has always prayed that all protestants would return to the Church that Jesus Christ founded for their salvation.
The Catholic Church interprets the Bible to say that it was started with St. Peter, who was the first Pope.
When they say in the Apostles creed "I believe in the holy Catholic church" they don't mean the Roman Catholic church, which is odd in that the Roman (Latin rite) Catholic church is the TRUE church. If they were to say the Nicene creed which goes.....I believein one holy Catholic and apostolic church....they would have a problem in that they are not apostolic, that is not ordained directly in line from the apostles which catholic priests are. Realising this the Anglicans have changed the definition of Apostolic to mean following the gospel message(s) as originally preached by the apostles. In short Anglicans (low church, liberal church and hight church) are really protestants pretending to be Catholics.
On Easter Sunday. Ash Wednesday exactly 40 days before
The NICENE CREED
It means that the 4 marks of the Church as spelled out in the Nicene Creed - One, Holy, Catholic and Apostolic - are found only in the Catholic Church. Other sects may have one, two or three of these marks but only the Catholic Church possesses all four.
