The 4th Beast of Daniel = Beast of the Sea = Pagan Roman Empire was spiritually "defeated" (converted to Christ) in the 4th century AD.
History shows us that pagan Roman Empire was converted to the papal system which did not follow the teachings of Jesus instead adopted the pagan form of worship which it still does till this day and will till the second coming of Jesus Christ
No other God
When Constantine moved his capital to Constantinople (330 AD), the Pope inherited the power, prestige, and even titles of the Roman emperors. The most significant of such titles is
Pontifex Maximus, a pagan title that means “Bridge builder between heaven and Earth.”
In 538 AD, the emperor Justinian issued a decree, proclaiming the Pope to be supreme in religious matters. Since then, the Pope has assumed the garb of representative of Jesus Christ on Earth.

worship Idols
There are statues in abundance; there are relics, such as bone fragments, said to have belonged to certain saints. Some shrines even contain pieces of wood purported to be part of Jesus’ cross. All of these things are held to be sacred objects worthy of high regard. The idolatry is rampant and fairly obvious to non-Catholics, yet Catholics do not believe they are committing idolatry. They have been cleverly taught to believe that they do not worship these idols; they simply “venerate” them. The problem is that “veneration” still gives honor and reverence to something and/or someone other than God; therefore, veneration is idolatry.

The Lords name in vain
Exodus 20:7 “You shall not take the name of the LORD your God in vain, for the LORD will not hold guiltless anyone who takes his name in vain.
Matthew 23:9
And call no man your father upon the earth: for one is your Father, which is in heaven.
Roman Catholics are taught to address their local parish priest as “Father” from the time they are a small child. They will continue to address their Catholic priests as Father until the day they die, unless of course they get saved, and are delivered out from that deceptive system.
Remember the Sabbath Day
In the 16th century a papal council plainly declared: “Let all Christians remember that the 7th day was consecrated by God, and hath been received and observed not only by the Jews, but by all others who pretend to worship God. Though we Christians have changed their Sabbath into the Lord’s Day.” REFERENCE: “Discourse in Six dialogues on The Name, Notion and Observation of The Lord’s Day”, Thomas Morer, pp. 281-282
“…by observing the Sunday change (the Protestants) are recognizing her power.” REFERENCE: “Plain Talk About The Protestantism of Today”, Mgr. Segur

Sunday was the day of the Sun god. In pagan theology, the Sun was the source of life, giving warmth and illumination to mankind. It was the center of a popular cult among Romans, who would stand at dawn to catch the first rays of sunshine as they prayed.
