To Catholics, there is no other religious service more important than Mass, which is a non-bloody re-enactment of Yeshua’s sacrifice. However, God is not satisfied with this external ritual.
And the same happens nowadays: a formal religious service giving due consideration to all rites and customs, demonstrating to the world the union with God whilst the heart of the individual is far removed from this close bond with Him. It is just pretence and deception; there is no longer any truthfulness in people’s way of life. (The Word of God, Proclamation 8686)
I Am not satisfied with the fact that you perform external rituals and acts in the belief that I Myself will then be in you, that you unite yourselves with Me when you take part in the ceremonies which you understand as the Lord’s Supper, as Holy Communion. (The Word of God, Proclamation 7909)
According to Paragraph 2181 of the Catechism of the Catholic Church, not going to Mass is a grave sin.
The Sunday Eucharist is the foundation and confirmation of all Christian practice. For this reason the faithful are obliged to participate in the Eucharist on days of obligation, unless excused for a serious reason (for example, illness, the care of infants) or dispensed by their own pastor. Those who deliberately fail in this obligation commit a grave sin.
For this reason, some Catholics continue to go to Mass, even though their hearts are not in it. Catholics have been taught the wrong doctrines all their lives. They are afraid to question, not to mention part with, these wrong doctrines, in the fear that they may go to Hell if they dare to do so. And so they will remain in error until they are enlightened by grace.
Nowadays people will not want to part with the doctrines handed down to them by people either and will therefore always remain in error, because they refuse to accept the pure truth which can only be granted to them from above, from the Eternal Truth. Yet such a gift of grace requires free voluntary acceptance. The truth cannot be forcibly conveyed to people who are unwilling to accept it. And therefore it is difficult to root out misguided teachings even if these are substantiated and amended to them as being wrong. (The Word of God, Proclamation 8686)
As long as they remain in their wrong thinking they will not be able to partake in the bliss of the kingdom of the beyond, which can only ever guarantee enlightenment. (The Word of God, Proclamation 8686)
Yeshua never instituted Mass, a man-made religious service that is utterly worthless in the eyes of God.
And you, who receive the truth from God, shall challenge this pretence of worship and remember that even Yeshua during His life on Earth did not support those who upheld wrong doctrines and tried to justify their pretence of worship as the only one pleasing to God and who condemned everything that contradicted their teachings. (The Word of God, Proclamation 8686)
The importance of enlightening you regarding the contamination of the doctrine which is supposed to come from Me is shown by the fact that people who mainly observe human additions are ignoring My teaching. (The Word of God, Proclamation 8829)
As soon as you realise that the sole purpose of your earthly life is your transformation into love, you will understand the significance of My teaching of love and liberate yourselves from all ceremony which, in My eyes, is nothing but ceremony, worthless formality. (The Word of God, Proclamation 8829)
God wants us to transform ourselves into love, not attend worthless services.
What then is the use of such “divine service” where you fulfil duties which I cannot value? And you believe you can make up for all your heartless actions by more eager church going and fulfilment of performances invented by men. (The Word of God, Proclamation 8829)
Your thinking will be right, your spirit will teach you from within, and you will free yourselves from all wrong doctrines. You will seek solitude more often and receive a richer blessing than by the “divine service” in which you now participate. (The Word of God, Proclamation 8829)
You people only have one way to achieve maturity of soul on Earth: you have to live in love. Thus you can do what you like; you can zealously observe the laws decreed by people, you can comply with all regulations which are supposedly necessary, but your spiritual development will not progress one iota if you disregard love. (The Word of God, Proclamation 7690)
You live a wrong life if you feel committed to denominational customs and traditions, to ceremonies and implementations of duty; you are wasting the energy of life which is given to you by Me for gaining spiritual strength on Earth, and this can only be acquired by deeds of love. (The Word of God, Proclamation 7690)
How can you humans reconcile My wisdom with what you have built, with what you believe to be the “Church of Christ”? How could I find pleasure in traditions and customs, in activities which are presented to you as “My will”? I can and will only take pleasure in those carrying out works of love. (The Word of God, Proclamation 7690)
Going to Mass will not lead us to God; doing deeds of love will.
