Is communion important for Faith/Salvation
In so far as it conveys God’s graces to us, it is. We need to continually draw on God’s grace in order to persevere in our faith.
How important is communion for your Faith, Does Jesus require us in the gospels to participate in the Body and Blood of Christ?
**It is very important to my faith for the reason I cited above and also to maintain a personal relationship/devotion for Our Lord.
Jesus instituted communion as his last act before entering into his passion. It was very important to him!

Through the Eucharist Christ remains with us until the end of time. The Church recognizes this and so makes attending Sunday Masses and Holy Days of Obligation mandatory. We are not required to receive communion except once a year, if we are able.**
