Sins are serious when they prevent you from receiving the sacraments.
Mortal sins are more serious than venial sins, and they have more serious consequences: With mortal sin, the life of grace is lost and the sinner is in danger of hell. With venial sin, the life of grace is weakened but not lost. Even so, venial sins should not be taken lightly, since habitual venial sins can harden one to commit mortal sin.
The Pentitential Rite at the beginning of Mass is when we confess our sins and are absolved by the priest's blessing of venial (less serious) sins. Mortal (serious) sins must still be confessed in the sacrament of Penance (Confession).
CAPITAL SINS are the sins that can lead us to more SERIOUS sin. The Capital sins are Pride, Avarice(greed), Envy, Wrath(anger), Gluttony, Lust, and Sloth(being lazy).
The ten commandments qualify as the most serious sins because mostly everyone knows them. It's the law. Grave sins mentioned in the Bible are the worse.
In many religious traditions, sins are generally classified as venial sins (less serious) and mortal sins (grave offenses). However, the specific types of sins can vary between different religions or belief systems. Common examples include sins of thought, word, and deed, as well as sins against others or oneself.
Catholics must confess their sins to a priest as this is the only normal way in which Our Blessed Savior left for people to have their sins forgiven. Less serious sins (venial sins) may be forgiven with a good Act of Contrition and Holy Communion. Serious sins (mortal sins) may only be forgiven at Confession. Besides the Church requires that all adult Catholics must go to confession at least once a year, even if they have not committed any mortal sins. Any good Catholic who is sincerely trying to fall Christ and become perfect (Matthew 5:48) should be going to regular confession, weekly or at the least, every other week.
In Islam, the sins that are considered unforgivable are known as the major sins or "al-Kaba'ir." These include shirk (associating partners with Allah), murder, falsely accusing chaste women of adultery, and disobeying one's parents. These sins are considered very serious and require sincere repentance for forgiveness.
No, not all sins are considered equal in the eyes of God. Some sins are considered more serious than others based on their impact and intention.
The punishments associated with the 7 deadly sins are often depicted in religious teachings as leading to spiritual consequences such as eternal damnation or separation from God. These sins are considered to be serious transgressions that can result in punishment in the afterlife according to various religious beliefs.

You should never approach to receive Holy Communion if you have not been to confession and are in a state of mortal (serious) sin. To receive Holy Communion in a state of serious sin, is sacrilege, and another very serious sin. Very serious sins include missing Mass on any Sunday OR Holy Day of Obligation. Church law requires that you go to confession at least once a year, even if you have no serious sins on your soul. If you haven't been to confession the last Lent or Easter, that alone would be a serious sin that would keep you from Holy Communion. Also being Catholic and not educating yourself correctly in the laws and rules of the Church would be a serious sin. Not knowing that you shouldn't receive Holy Communion in a state of sin would qualify. You should discuss this with the priest in the confessional as soon as possible.
Yes, it ensures that all the sins you confess are 100% cleansed from your soul. You remove all the things that block you from God and you ask for His mercy. It can remove even Mortal sins (Sins which are serious and you do deliberately even when you know that it is wrong). So yes, reconcilliation is a VERY good thing, and you should go often, especially around lent and easter.
