Is it true that if you miss Mass through your own fault (too lazy to go or something else to do for example) that if you die before you get to confession, you’re condemned to hell?
It is in fact **incredibly easy **to go to heaven, for we are all created by God with an immortal soul meant to go there, and the Son of God underwent what He underwent for our sake, so that everyone who wants to go to Heaven can go there if he wants.
Mortal sin is a grave injury to God done with full knowledge and deliberate consent. Holy Church has been given authority by Christ to teach, and when Holy Church commands that the faithful attend Holy Mass on Sunday (or Saturday Vigil) and every Holy Day of Obligation, she does so by the authority of God. To disobey out of laziness or preferring to do something else is not to offend the Church, it is to offend and challenge the living God. If a messenger of the king comes and tells me: there is a feast every Sunday to commemorate the King’s wedding, you have to come. Yet I don’t go, because I don’t respect the messenger or I don’t think his order binds me to obey, I am actually offending the king.
Any mortal sin, by its nature, is us rejecting God. If we die, such choice becomes eternal, meaning outside of time. We cannot change our mind after death. What is most hurtful is this - and it is a great mystery: after death, the soul that rejected God and finds itself in Hell is aware that the living God still loves her of an infinite love and is always open to forgive, and that she, the soul, is the one who rejects God, not vice versa. That God did not judge her and condemn her, but, rather, that she judged herself and condemned herself, despite the fact that God in fact came to live among us and told us very clearly:
I do not judge anyone. I came not to condemn the world, but so that the world would be saved through me. I do not call the righteous, but sinners to repentance.
We have a problem: we don’t quite understand what the Church is. The more we learn about Her, the Spouse of Christ, our Mother and Teacher, the more we understand why Her precepts are so important for our salvation. And also we don’t quite seem to understand what Holy Mass is, especially on the Lord’s Day, in English called “Sunday”. Perhaps if our eyes were unveiled and we saw the Blessed Virgin at the foot of the altar, prostrated, and the seraphim at the side, covering their eyes in awe, and Christ Crucified on the altar, and our own guardian angels bringing up to heaven our prayers, and the entire heavenly court around us, angels and saints, in the unity of the Holy Spirit, perhaps then we’d understand why it is such an offense to not attend Holy Mass when we are called to be there.
That is not to say that if a person has serious, grave reasons that prevent him from attending, he is in mortal sin. There are even dispensations for truly serious ongoing circumstances (ex. an illness that forces us to be in bed). And the Lord is so humble that He commanded His Church to bring Him to you in such a circumstance…the living God comes to you if you cannot go to Him…and will you then prefer to do something else other than going to Him when you are invited to do so?
Going to heaven is easy, for Christ, truly God but also truly man, showed us how. He shared with us something that was unique between Him and His Father: the Holy Spirit. Through this ineffable gift, we become more than men: we become partakers in the divine nature! Christ not only did this, but revealed that which perhaps is the greatest of all divine mysteries, and the highest of all truths: that this grace fulfills the law! So each and everyone of us, baptized in Christ and purified through Reconciliation as needed, can do all that is needed by simply loving God and our neighbor with the purest, simplest, self-giving unconditional love that forgives everything and expects nothing in return!
I suggest you read “Story of a Soul” by St. Therese of Lisieux, Doctor of the Church (“Doctor of Love” is her title). Her
little way to holiness is a masterpiece that greatly helps souls who consider that there should be an easy way to do God’s will and finally be with Him in heaven.
