Franz:
…How can I explain that this is an obligation that I must follow or my soul is at stake because it would be a mortal sin, and their service isn’t good enough???
I guess that although I agree that the Mass is more reverant, sacred, beautiful, fulfilling (for the Catholic that believes in the Real Presence), I can’t agree that I’m not keeping holy the Sabbath byt attending their service. It’s only my opinion, so please don’t shoot me.
The Eucharist makes the difference between a Protestant “worship service” and the Holy Sacrifice of the Mass like the difference between night and day. It’s like comparing apples to oranges. At the mass, heaven comes down to touch earth - we worship the Lord - body, blood, soul and divinity - with choirs of angels and saints. This, I’m sorry to say for our well intentioned separated brethren, just ain’t the case in the Protestant world.
When you start to see the mass as it really is, all personal dragging of the feet stop…you start to look for ways to go to mass more often. The weekend won’t come soon enough

!
All that being said, the obligation of Catholics to attend mass is set forth by the Church, who have the powers to bind and loose given to them by Christ Himself. All the difficulties you may have is secondary…the one’s with the authroity given to them by Christ have “bound this” …so it’s bound in heaven.
The
old Baltimore Catechismlays it out plain and simple:
**279. Whence has the Catholic Church the right to make laws? **
The Catholic Church has the right to make laws from Jesus Christ, who said to the apostles, the first bishops of His Church: “Whatever you bind on earth shall be bound also in heaven.”
*Amen I say to you, whatever you bind on earth shall be bound also in heaven; and whatever you loose on earth shall be loosed also in heaven. (Matthew 18:18) *
**280. By whom is this right to make laws exercised? **
This right to make laws is exercised by the bishops, the successors of the apostles, and especially by the Pope, who as the successor of the chief of the apostles, Saint Peter, has the right to make laws for the Universal Church.
*And I say to thee, thou art Peter, and upon this rock I will build my Church, and the gates of hell shall not prevail against it. (Matthew 16:18) *
Peace in Christ,
