To adore God means to worship him as our sovereign Creator and Lord, avoiding the sins of idolatry and sacrilege. We exercise faith by believing in God and all he has revealed, and by witnessing to our belief by the way we live. A strong faith calls us to make the effort to develop and grow in it. A Catholic sins against faith by joining a non-Catholic church, by denying a truth of faith or by being indifferent to the Catholic religion. Fight the good fight with faith and a good conscience.
Heresy is the deliberate denial of a truth of faith.
Apostasy is complete rejection of the Christian faith by a baptized Catholic. We need God s grace to live good lives. We must confidently hope for his continued blessings until we enter his presence. We can sin against hope by presumption and despair. Presumption is the sin of expecting that God will save us without any effort on our part, or presuming that we do not need God s help to reach heaven.
