I believe faith has nothing to do with the kind of religion you are a member of. Since we came to this world naked, we are all equal, no influence, no belief, purely human-- from One SAME God.
I was baptized a Christian and brought up with Christian values and virtues. Had my first step and last step of knowledge in Christian schools. In my years of learning the facts and hearing the opinions, I can't resist my amazement and respect on others beliefs and practices. One of which is--the FAITH AND DISCIPLINE of Muslim people.
Today is a national holiday in the Philippines. A 'lil info for those who doesn't know, Christianity is NOT the first religion of the country but ISLAM. This day is given as an opportunity for us Filipinos to celebrate with our Muslim brothers.
Eid is an Arabic word meaning "festivity", while Fiṭr means "conclusion of the fast"; and so the holiday symbolizes the celebration of the conclusion of the month of fasting from dawn to sunset during the entire month of Ramadan . (taken from wikipedia)
Idul Fitri is not only for celebrations but a time for atonement: to ask for forgiveness for sins which they may have committed but was cleansed as a result of the fasting in the Muslim month of Ramadan.
