There are many reasons for being a Catholic and we will answer some of those reasons for you. Many people return to the Catholic Church whether Roman, Russian, Greek, Bulgarian, Brazilian etc because they feel an intense longing for the Eucharist. Mostly it may happen at a wedding, funeral, confirmation or baptism, but we see mostly when people are alone or facing difficulties in life, most people have described it to us as a deep hunger for spiritual nourishment that comes within when the receive the Body and Blood, soul and divinity of Jesus Christ.
This hunger for the Eucharist triggers recognition of the presence of Christ in other sacraments, which draws them even more deeply in to the practice of their faith. It is without exception any reason for anyone to be a Catholic.

The Catholic Church offers all union with Jesus Christ in Scripture and in prayer not forgetting in the community of others, in the Eucharist, and other sacraments, it offers full spiritual support in good times and bad, with divine wisdom that is thousands of years old, not forgetting it offers meaning and purpose of life after death. You will know that you are at home and peace when you feel that deep sense of understanding and peace.
Being Catholic just does not end there, many people seek a true sense of belonging, but a community is more than just friendly people, good sermons and activities. A Catholic Christian community is a group of people who gather around the person of Jesus Christ to worship God and live in the light of the Holy Spirit.

Catholics come together at Mass, in the sacraments, and in parish activities to pray, celebrate joys, to mourn loss of loved ones and to provide support with there desire to serve others by adding that extra strength in their daily life’s, not forgetting the importance of recognizing of walking with others towards the union with God.

So, yeah, I didn't come up with all that, cut its a frequently asked question.
